Ah, well I'm in a similar situation as you, I really am not going with the flow of modern anime fans, not too well, heh. I follow games a lot also. There are a few big ones I like, like Fullmetal Alchemist and Death Note, but those are about the biggest ones.
Other Games/Anime/Manga I'd buy from are: Final Fantasy, Wolf's Rain, Azumanga Daioh, Akira, Outlaw Star, Requiem from the Darkness, Ninin ga Shinobu-den (this one would be absolutely awesome, haha), Ragnarok, Detroit Metal City. There are more, but these are what I can think of at the moment.
