Accel World

Anime starring a group of friends or classmates.

Anime series that take place inside a virtual game world, often by playing a virtual reality game (VRMMO) with other players, or by being transported into a new world with videogame rules, RPG stats, levels and other game-like elements.
The first shows in this stack are pure VRMMO anime where the protagonist plays a VR game, while shows further down the list are other types of virtual worlds or isekai worlds with game mechanics.

You go to, or use a electronic terminal, "warp", go. Full VR Immersion ensues.
Or your world needs to run on internet Infrastructure. At least a relevant part of it.

Not complete by any means, but it's there.

Using here a more loose definition of a Metaverse, as made by a group, or some organization.

From the Snow Crash story: "When Hiro goes into the Metaverse and looks down the Street and
sees buildings and electric signs stretching off into the darkness,
disappearing over the curve of the globe, he is actually staring at the graphic
representations -- the user interfaces -- of a myriad different pieces of
software that have been engineered by major corporations."

note: i did not watch majority of these, this is just a compile of some lists i found online

i will also not add any who are obviously offensive

These anime fit into either of the following categories:
- Virtual Worlds
- Highly Advanced Futuristic Technology
- AI's (Artificial Intelligence)

Here's some of the anime series that deals with mafia,gangsters,delinquents etc.

This list contains some Anime series about characters in gaming setting whether video game, gambling or even tabletop game. If you are into this type of Anime, then you're in the right stack.

I am not sure why I am making this stack. I think the reason is I like a person if he/she is a little chubby.
And if you want to workout becoming fit these animes can inspire you.

Also These list of animes have a unexplained similarities in them. The main character in all of them shows same characteristics like being kind, safe reliable, honest.... Maybe those are the chubby guys qualities.

[To increase this list, my DM's are open so suggest me but please remember that the anime story should be held around the chubby guys, if a chubby guy not the main of semi-main character don't suggest me that]

List of some animes about games

Yes that series has a game/ is a game. As I collect anime games I want to help people find games for series they enjoy. No this is not related to mobile games, maybe I’ll do a stack for those in the future though🤔 These are tied to Console and PC systems, I won’t list specifics though but searching “[insert series] game” will help you find it. There will be multiple parts coming out!

tokusatsu/henshin hero inspired anime

Animes where the protagonist has some type of disability, illness or mental problems.

Animes with fake McDonald's brand names.

List of anime series that are VRMMO, Isekai that's inspired by a video game, or a series that has leveling up and dungeons.

anime where some of the major characters have exceptionally long, pretty, black or dark-colored hair.
generally anything shorter than waist length won't make the cut, because there are so many.

Also some of these didnt properly adapt manga but the anime finished with their original ending (in those cases).
These are just the ones I'm aware of, This list will keep getting updated.

Be sure to watch the remaining Seasons,Ovas and Movies. Didnt include them here due to cluttering.
