I've never been a great FPS player, but I do enjoy the genre, or at least I used to. (Apparently, kids these days think camping at spawn points is cool. In my day, that would get you kicked.) I really liked BF2. I liked hopping in anti aircraft batteries and gibbetting whole groups of people until inevitably someone stuck a bomb on the back on detonated it. Loads of fun. When I got BF3, I thought, "What the fuck is this?" Every gun, every add-on had to be unlocked. It was stupid, and made an already frustrating game, unplayable. I was a goddamn sniper, without a goddamn scope! WTF?
Even the single player campaign was boring and by the numbers. It was almost as bad as a rail-shooter, that I couldn't bother to finish it. And that's when I realized that I'd probably never play another FPS. (Well that, and the stupidity of the COD Black Ops demo where I had to walk to a U2, climb up a latter, turn on the plane, fly up, then watch a cut scene. Pointless.)
