For those of you who missed Splinter Cell: Double Agent -- or simply haven't had the time -- a single player demo is now available* on Xbox Live Marketplace (it looks like a College Hoops 2K7 demo is up as well).. I am loth to admit that I am one of those who have not played Double Agent at all. I think I had Enchanted Arms on my rental queue at the time (oh, if I had only known!). Still, if you haven't had a chance to play, or if you're just the kind of person who needs a demo to make purchasing decisions, now is your chance. The demo clocks in at about half a gig, so find something else to play while you're downloading. Here's a suggestion: just watch the Halo 3 ad over and over again until the download completes.
