doom 3 was an okay game
RPG is so-called not because of the presence of role-playing per se, but rather because of the presence of game mechanics that originate in tabletop role-playing games such as D&D.
Character progression, class-systems, inventory/party management, and the like make a game an RPG, not the idea of taking on the role of a character (which is ubiquitous - you play as Mario in his games, for example).
