Wiki if you don't know what Comiket is.
Thought I would make this thread as a place to post info on anything good that comes out at C82.
Here is a blog post that has a bunch of info / screens / videos about (mostly) Touhou games coming out. Tenjou's Tempest looks okay.
A good time killer though is /!\this video/!\ which is over an hour of trailers for games that will be released.
Some of the games:
Astebreed Site, Trailer
Revolver360 Site, Trailer
新世紀GPXサイバーフォーミュラSIN DREI Site, Trailer
Anyway not a whole lot of info on any, but hopefully there are some things people find interesting.
