What's your fav video game based animes?

My fav video game based Аниме is Sonic X! No, not the lame TV-Y7 rated 4Idiots version. The... Oh, sorry. Let me correct myself. The 4Kids version. I mean the REAL TV-14 rated Japanese version. With all the detail, all the profanity, all the blood and death scenes, all the SIGNS and all the Любовь and emotion that sets the tone. So what's UR fav video game animes?
