Okay, I'll admit I have a heavily modded XBox. Actually, even if I didn't, I wouldn't pay to use XBox Live. I have a problem with money of mine going to M$ - which is why I bought a used XBox and 3rd party controllers.

Trouble is, I don't know anyone else who uses it (though there seems to be around 1,000 players on the network at any given time). Anyone out there who does use it, or is willing to give it a go? Basically, you can play any game that supports System Link over the XLink Kai network. Here's the page:
