So what you're saying is you'll be buying a rehashed sequel, a sequel, a sequel, a sequel, a sequel and shock horror, another sequel.
Way to make a point about how PC gaming isn't dying.
I don't think its dying, but it is becoming less varied. Back in the heyday, we had a glut of everything from flight sims to FPS's and everything in between, but with typically short lifespan on most games and hardware.
Nowadays I can play pretty much anything I want to on a 2 yr old 8800GT, (admittedly im pondering and upgrade) and a lot of game genres have become console ports, or largely disappeared from the PC. Thats because theres money in the consoles, and less in PC's.
Of the 5 gamers in my IT based office, 3 of them play on consoles. In other offices (largely older guys, typically mid 30's) there arent any PC gamers.
That said, the PC will remain the best platform for FPS and multiplayer, for the forseeable future. As long as devs dont get hyper-greedy and keep dedecated servers in games.
