I have one of the last XP machines left on the market, which I grabbed for a bargain at Wal-Mart last year. The first games I installed were SCF2 and OP along with the updates. I went looking for a server that was inhabited, and there weren't any. I installed ME2, RoN, the entire Civ4 package(which is kinda boring), and the oldie, but still a goodie, Sid Meier's Pirates!, which is still, next to SFC, my favorite game, and the one I still play when I burn out on the others.
I have faith that DH, and the rest of the braintrust, will figure out a way to make it work. It may not happen next week, or next year, but as Billy Joel once said, I'm "keepin' the faith!"
