At least for a while. That's not to say I won't keep playing what I own. I'm really enjoying Gears 3 online and local, and I still play Black Ops + Bots with friends on the couch. Team Fortress 2 with its addictive loot system can keep me going for a while on PC as well. We even pop in Halo: Reach every once in a while for some four player Infection on custom made maps....
But I think that's it. I have enough. These games are made to be replayed, and that's what I'm going to do. Replay them. I'm not buying more shooters. Certainly not outside of extremely low used costs (under $20) or Steam sales. Frankly, the removal of bots and four player splitscreen from most shooters has dampened the funnest part of the genre for me, which is playing socially with real friends in one room talking trash and getting trashed. Sorry, but online just doesn't make up for that.
So, does anyone else feel the same?
Edit: To clarify I'm referring to military multiplayer shooters, not hybrid games like Bioshock Infinite, Uncharted 3, RAGE, Half-Life, and Borderlands. These use shooting as a combat mechanic but also feature other combat and gameplay mechancis, such as exploration, customization, and puzzle-solving.
