I found out yesterday that Street Fighter IV is available for PCs. I've got to check my computer's specs because I'd love to be able to get that game but I'm not ready to make an investment in an XBOX just yet.

However while researching SFIV I found out that Marvel vs Capcom 2 is being released (as a download) for PS3 and XBOX. If you've got either console I'd recommend it, I've got the PS2 version and it's great fun although the final boss is a bit tough unless you have the right trio of villains. As a Marvel Comics fan I love that it has very Marvel character that's been in a Vs game plus a few bonus ones.
