MMORPG/RPG players are more my type, mostly because those are the genres I enjoy the most. Unless they're rabid and psychotic. There are gamers of those types in every genre, so I don't think its fair to judge an entire genre's fanbase based on those people.
Being the self-righteous and jingoistic PC gamer I am, I tend to scoff at shooter discussions, mostly because, while I know there's more to it, it just seems so shallow to me. That's just my opinion though, and this is someone who's been raised on the Ultima series and Dungeons and Dragons, and similarly nerdy prospects.
