I decided to plump for Streetfighter IV. Ashes 2009 isn't out until next Friday and I just remembered that someone's giving me the ?20 I lent 'em back this weekend as well.
?17.99, play.com.
Edit: I hope I don't get any problems with Games for Windows Live - I've never used it before.
I've had no problems, it has actually worked really well. I already have afairly large friend list and am able to contact, and meet up with friends easily.
I forgot to ask one fairly important question: how will it run on my system? :doh
Can You RUN It? hasn't got it listed yet.
