Lara Croft Guardian of Light (stop me guys if I am spelling or naming it wrong) is the Xbox Live Arcade Download Only game that is a bit like a dungeon crawler, its pretty good but its more top down (Or maybe a hibred top down/side view) game that is available via XBLA, Its nice but I got bored of it a bit quick. You might like it!
I've been loving my 360 for about 5 years, play it all the time, its only recently that I've gotten a second wind with the Dreamcast, I guess I just give it a rest for a few years but always come back lol. I was going to buy Duke Nukem but am glad I held off, really dodged the bullet on that one! lol, anyway yeah Enslaved and Crysis 2 are my main games at the moment, oh and Sega Mega Drive ultimate collection
