This rating is as much about the game as it is about the devouring of itself. This game is important because it's this game, but also because it's dozens of others. It's not the first game to be like that (Doom & Quake) but I feel like it's the most successful at it. This is also a five star for Counter-Strike, Day Of Defeat, Firearms, Front Line Force, Sven Coop, Natural Selection, and everything in between. It's a game that's also a platform, and to my mind it's the most successful version of it.
