Because, the only good one was Resident Evil 4. Most of these games follow the foot steps of gears of war. By that I mean being shitty and bland. All you do is cover and shoot (with a really really forced cover system). There are no puzzles or exploration. Just really slow shooting. Only good for coop and multiplayer.
And don't even mention Uncharted. Uncharted is a platform game with shooting. Like Tomb Raider.
