If you like "No Game No Life", then you might enjoy...

Yagami Light is a 17-year-old genius from Japan.

One day he stumbles upon a notebook with the words "Death Note" written on the front. Unbeknownst to Light, this book used to belong to a Shinigami called Ryuk.

Shinigami are Death Gods.

The first sentence in this book states that anyone whose name is written inside will die.

Light falls for his all too human curiosity, and try to write in the book. Discovering that those whom he writes into the book actually dies, Light decides to use this power to change the world.

Light will change the world in his image and become God of the New World.

Light soon meats resistance from another genius known as L. He is working against Light's beliefs and Light himself.

Death Note is a really good anime.

This might be a good starting point if you never have watched animes before. If you have experience with animes then you probably already have watched this show.

Death Note is not an Isekai anime, but the main character is clever and ruthless. Light from Death Note is a pure villain. Death Note is not comedic and has a much darker tone, but both main characters are clever and use their intelligence to get ahead.

MMORPG gamers find themself transported into the game they play.

Shiroe and the others in Log Horizon attempt to live their lives out in the new world they find themselves trapped in.

They form governments, deal with NPCs and other players.

Log Horizon is a very good anime. It`s about more than simple fighting.

Log Horizon also centers around people stuck in a game world. The main characters adapt quickly and intelligently to the situation and are very powerful. Log Horizon is more serious and has less comedic and fan service elements.

Momonga is a powerful wizard and master of the dark guild Ainz Ooal Gown int the popular virtual reality game Yggdrasil.

The final hour before the game shuts down for god has come and he decides to stay logged in during this event.

To his surprise, despite the clock having struck midnight, and all the servers should have been shut down, Momonga is still fully conscious inside his game character.

What's even more strange is that all the NPCs appear to suddenly have developed personalities of their own.

Surprised by this strange occurrence, Momonga decides to investigate and take control of this new world to figure out the cause and to see if there are others like him.

I recommend this anime, but only if you like this genre. Its one of the better "trapped in RPG game world" animes.

Overlord also has a main character that is trapped in a game world. They both want to take power in this new world, and they are both overpowered. Both animes are Isekai. 

Sword Art Online (SAO), a massive online role-playing game, is launched.

It uses "NerveGear" technology, a technology that lets players control their avatars within the game using nothing but their own thoughts.

Kazuto Kirigaya is one player among ten-thousand others that logs on to SAO as it launches. He was a beta tester for the game, so he has a leg up over most of the others.

The players soon realize they cannot log out. The game’s creator has trapped them in his new world until they complete all one hundred levels of the game.

The animation and sound work is good. Sword Art Online worth watching, but only if you like this kind of animes.

The main characters from both shows are gamers that are transported or trapped in another world. Both shows are of the Isekai genre.

Lelouch Lamperouge is an abandoned prince of the Holy Britannian Empire. He hides his true identity as a student in the colonized territory of Area 11, formerly known as Japan.

He acquires the power of "Geass" from the mysterious girl named C.C., which enables him to command anyone to obey his orders.

After obtaining the "Geass" he starts to wear the mask of Zero and begins his rebellion against his own father's empire. He wants to take revenge for his assassinated mother.

Code Geass is an excellent anime. It is one of the better animes I have ever watched.

Code Geas is not an Isekai anime. But both main characters are geniuses and master strategists. They both also love games.

Satoru Mikami s a typical Thirty-seven-year-old corporate worker. The only thing he misses in his life is a girlfriend, otherwise he is is perfectly content with his monotonous lifestyle in Tokyo.

During a regular encounter on the street with a coworker, Satoru is suddenly stabbed by a random assailant. While he is dying he hears a voice in his mind reciting a bunch of commands that he can make any sense of.

When Satoru awakens he discovers that he has reincarnated as a goop of slime in an unfamiliar world. It's a game-like world with skills and stats and Satoru has gained the power to devour anything and mimic its appearance and abilities.

Satoru meats the sealed Catastrophe-Level monster Storm Dragon Veldora who had been sealed away for the past 300 years. Satoru befriends him and promising to assist in destroying the seal. In return, Veldora gives Satoru the name Rimuru Tempest to grant him divine protection. In this world name has power.

Rimuru starts his journey in the world and as he grows accustomed to his new life his actions ripple throughout the world and gradually alter his fate.

That Time I Got Reincarnated as a Slime is a good Isakai anime. 

Rimuru becomes somewhat overpowered but he is a fine central character. It a decent story where Rimuru meats interesting friends and build a community.

Wade Watts is a poor teen living with his aunt in the stacks, a trailer park with the trailers stacked atop each other. A place for the poor.

Wade only feels alive when he`s inside the OASIS, a popular online game that most of the world is obsessed with.

Even with the basic headgear and gloves, it's almost like you are inside the game. It gets even better for those with the money for specialized bodysuits.

The creator of OASIS, James Halliday, told everyone before he died that he had hidden an easter egg inside the game. And whoever finds it first will inherit his entire multi-billion-dollar fortune.

Wade is among the most dedicated hunters that label themselves as gunters. To find the egg they study the life of Halliday, especially his earlier days in the 80s. And gunters are really dedicated to their studies.

When Wade is the first to find the first clue thing takes a nasty turn when he discovers that people are willing to kill him in the real world to get it.

This book is full of pop culture from the 80s, especially the cool nerdy stuff. Sadly I`m a little too young to have experienced the 80s pop culture, but I know some of it, and it is still cool.

It is all those references that make the book shine the most, Ready Player One would not be as good without it. Other VR themed books are better.

In Rady Player One lots of the story take part in the real world, and they are not stuck in a game world.

Jason attends a prestigious private school and his parents are reasonably well off. But his parents are never home, and he is bullied by both students and faculty at this prestigious school.

Frustrated with his life, Jason escapes into the newly released full immersion VRMMORPG game Awaken Online.

Jason quickly finds himself on the path to be one of the game's greater villains. With his powerful necromantic power and newly won leadership of a new playable race, he becomes a target for all the rest.

Jason constantly logs on to the game for the freedom and power he gets in it. Something that he lacks in real life.

One of the reasons for Jasons growing power in the game is that one of the major AIs in Awaken Online has taken an interest in him, and in humanity.

Awaken Online online is one of the best LitRPG series.

Usually, I don't like LitRPG books that are too much in the real world. But in this case, Travis Bagwell has managed to keep that part interesting too.

Awaken Online has interesting game mechanics, and I like how the AI overlords interact with the game.

Awaken Online is an amazing book series that is absolutely worth reading, especially if you like LitRPG books.

Timothy has just started as a tester for the largest and most technologically advance VRMMORPG game in the world. The testers compete for some big reward by streaming their game. The tester with the most popular stream wins.

The company delegate the class and some skills for the tester to use. Their goal is both to test the less common combinations and to make them more popular. Timothy is given the goblin race with the herbalist class and put in a strange starting location.

Timothy and his sister secretly cooperate to make his chances to win the competition among the testers higher. She is both too young to work as a tester and disabled, so she has to join from their home.

Together they explore the game and make plans for dealing with the strange class and race combination. But it's not only in-game problems they have to overcome, but real-life dangers are also a problem.There is a huge award for the winner of the game

The Dark Herbalist Series is a LitRPG book series with a good balance. Game and leveling mechanics are well mixed with a solid story and character development.

The characters are not helped out by random events and Deus Ex Machina. Instead, they use out-of-the-box and quick thinking to get out of problematic situations.

The Dark Herbalist Series is interesting and absolutely worth reading if you want a LitRPG book series.

Martin Banks is a guy with an above-normal interest in computers. He loves nothing more than snooping on files he should not have access to.

One day he makes an abnormal discovery.

He finds a file that changes reality when he edits it.

Implying that reality, himself included, is nothing more than an elaborate computer program.

Every little tweak he dos to make his life a little easier does not go unnoticed. Rather than face prosecution and trying to explain what he can do, he decides instead to travel back in time to the Middle Ages and pose as a wizard.

I love the concept, and the humoristic story around it is marvelous. If you are afraid of laughing around strangers, then you should probably read it at home.

Sadly the third book was a huge disappointment, but the two first are extraordinary.

Cal is a Dungeon Heart, a soul forced into a magical stone against his will.

After several years of only instinctive living, he was able to regain his sentience. This allowed him to form new memories again, and to slowly start growing a dungeon around himself.

With help from a small friend, Cal learned to create monsters and traps and how to use treasures to grow his dungeon. His main goal is to lure in brave adventures to eat so he can grow in both power and size.

Dungeon Born is one of the best books I have read in a while. This book is written in a light and funny way. For me it was new and fresh, it was the first Dungeon Core type books I read.
