With my original Xbox, I really liked playing games with friends over Xlink Kai. I haven't yet done that with the 360, mostly because hardly anybody I know has an Xbox 360. I want to know how well the games play over Xlink Kai. Are they smooth ? Are any of them "watered down" like the last few Rainbow Six games for Xbox (no voice on System Link) ? I'm not looking for an XBL vs. Xlink Kai debate. Most of my friends rarely play games online so they won't be purchasing XBL memberships. When we played, we'd mostly play the Ghost Recon or Rainbow Six games in cooperative mode. Anybody who has played a decent amount of Xlink Kai / XBC on the 360, please provide feedback. Thanks in advance !
