YOU DA MAN! :D

I think this is more along the lines of the name of the genre being indistinctive, overly general or not helpful.

For example, other than the FPS (first-person shooter) games where your character is in a wheelchair, aren't each describable as a walking simulator? Or maybe a "walking simulator with a projectile launcher"?

And MUD is a multi-user dimension (or dungeon, even when not in a dungeon). Isn't that any multiplayer game? The MMORPG games might as well have been called video-MUDs.

I agree. That's very obscure to me because I think of what a rogue as a person is suppose to be. It seems like that term is a reference to a specific game named "Rogue" and therefore is not about the character but the gameplay itself, which isn't really distinctive to rogues.

Rollers of the Realm - pinball RPG! :)
(but I guess it is more like a hybrid then an actual genre...)
