Bump!
Thought it was worth revisiting this thread as PC gaming appears to be going through a bit of a renaissance at the moment. It's getting all the decent cross-platform titles, a decent smattering of the 360 exclusives and, of course, it's own fantastic exclusives like Crysis, Football Manager 09 (for now), Cryostasis and all the RTS games like Company of Heroes, CCRA: 3.
Get yourself a 360 controller and you've essentially got a 360 with better graphics and mods for games, plus a massive, massive back catalogue of PC games that dwarf all the last couple of generations of consoles combined.
Of course, piracy is a massive issue on the PC and I have been known to use 'evaluation' copies before buying a game, but if I do play anything for more than a few minutes, I will always buy it. No-one buys the games, no games get made.
Looking forward to Cryostasis and Mirror's Edge as well as the new F.E.A.R. - and currently 'rocking' Fallout 3, FM09 (superb, lost most of last night to it), Fifa 09, Mass Effect and the Crysis games.
Nice one, PC like BG. Especially as past criticisms, such as the cost of hardware, are largely irrelevant now. £300 will get you a rig that'll play most titles comfortably. And then of course, games cost £25 for new titles whereas they're £45 on consoles.
