Well, if you're coming back into gaming 100% cold, then why not sample some? Assuming you are good to go with a solid net connection, I'd get
File Planet (Demos...and Betas! A little of everything to make all gaming easier)
Gametap (A wide variety of games that install local but run through the service. Flat rate pricing)
Onlive (Like Gametap, but everything runs on their servers making local resources irrelevant. Connection is critical..and they carry current release
games as well as going back years. It also lets you watch other members there playing the same games in an 'over the shoulder' way)
One or a combination for even 1 month would give you a way to sample and play with everything a bit, before dropping $50-$80 on a current release
game. Just my thoughts...
By the way, Op..... Onlive has all of the specific games you listed. I play a couple of them there.
