What can I say, I'm a little late to the Xbox party. So this week, I just got a 360 (250gb, no Kinect), and I'm looking to the VGF for some suggestions. Yes, I've Googled various "Best of" lists, but not many people seem to focus on the exclusives. I already have a PS3, and some Steam goodness, but I'm looking for some suggestions on some good 360-only games to check out, whether it's retail or XLBA.
What do I enjoy? I really like "action/stealth" games (yes, I picked up Splinter Cell: Conviction on Steam a while back, as well as Mark of the Ninja), so Tenchu Z is on my list. I enjoy dungeon crawlers like Torchlight, Dungeon Siege 3, etc. I like the classic turn-based FF RPGs. I'm a fan of good twin-stick shooters, and third-person action stuff like Darksiders, Saints Row 3, and the Ratchet and Clank games. The console comes with Forza 4, so I'm set for racing for a bit, and I'll probably try the Gears series.
I know that there are several years' worth of older titles that I'm probably not even aware of. So aside from the Halo series...any suggestions?
