I'm kind of wondering that, I mean, games like Kingdom Hearts and Legend of Zelda look like in Anime style, and they both even have a Manga to go with them, so would they be concidered an Anime even though they're a game series?
Well If I remember correctly then anime is short for animation. So technically in the animation sequences of some video games they could be considered "anime," I guess, but I usually consider anime as just the actual shows. Good question! :)
