Come on, come all. Join in on the fun of coming up with and discussion of absurd anime ideas. "But proto, anime's done it all. But proto" No they haven't. They may have taken most of the glory, but there are some ideas that they (may have done, but not a whole anime dedicated to it) haven't done these at the very least:
Jenga!
Draughts/checkers (I'm sure many similar things have been done, but I have yet to see an anime dedicated to it)

Now the latter isn't really absurd, but I still for some reason have never seen it done. Which is sad. Jenga, though. I seriously want that.

Personally, I would like to see an anime based on fighting games (e.g. Street Fighter, Tekken, Guilty Gear...not counting Smash, they are their own thing) and the community that surrounds it.  I would say video game community overall, but there's something about fighting games, something about about going 1 v 1 that can tell a lot about the players in terms of skill and personality.  It would touch on gaming techniques, such as reaction speeds, stick+button inputs, and adapting to different play styles depending on character used.  The FGC has its share of drama, mostly due to clashing egos, trash talking, and money/grudge matches.

So here's a story:  A highschool student decides to pick up fighting games after his best friend, a legendary player, is killed in a car accident.  He quickly realizes that the fighting game community (FGC) is cruel and unforgiving, and only the best are given a shred of respect and support as well as sponsoring from major entertainment companies.  He makes new acquaintances, all who knew his late best friend.  After discovering he has a reaction speed much higher than the average human, which is commonly called "The Edge," they decide to train him.  The learning curve is steep, but he gradually improves through practice, suffering countless losses, placing top 8 in tournaments, and endless inspiration from the memory of his dead friend.  Then blah blah blah, he gets gud, beats the most skilled players, thanks to his "Edge," and barely manages to snag the World Championship after a close match up against another player with the same ability.  

Shit, did I just type all that?
