PC games haven't gotten any worse, console games have simply gotten better.
Leave it alone, the best games will always be on PC, because PCs are scalable, upgradeable, and will always be the most cutting edge platform.
I use a Logitech G25 Steering wheel for NFS Carbon, which means I play at 1280x1024 and it doesn't look grainy as hell.
I've seen HiDef gaming on a bigscreen. It's wild, but give me a 21" widescreen at 1440 anyday and it will look a lot better because it's not trying to do something it can't.
HDDVD? Computers have that too. Blueray? I think so, but haven't checked around...
If it's not, it will be available soon enough. It always is.
My point is that PC gaming will always be around and any game that comes out on console, that is any good, will be on PC as well. This is because any solid gamer owns a solid PC or a solid console, or both.
That said, I prefer Oblivion on my computer, with a keyboard, then a console, with a controller.
But if I'm so inclined, I can use my XBox 360 controller, on my PC. Customization, tailoring my experience.
Something consoles mimic, but cannot actually do.
PC Gaming isn't going anywhere. Consoles have become much better, but computers are always better.
