Well, while you guys were arguing, I downloaded the demo and played through it.
Despite the lacking MP demo, this SP demo just convinced me to buy this game.
It looks great on my GeForce2 with all the settings cranked way up. I was a bit dissapointed by the enemy AI, but the squad AI blew me away. Going through the demo on Medium difficulty (trying Hardest next) only 1 of my squadmates died, I only wish they would use grenades =D. They never got caught in doorways, or blocked me in a room. Kudos to 2015's AI devs.
So, quit your whining and go play this demo!
