I rapidly getting addicted to diplomacy (that's the game 'Risk' was based on, as compared to being nice to people, which is something I try to do, but I'm hardly addicted to it ;-)
A few fellow uni grads played a game that took six months. This was fun, but long. We've just started another game, and it's taken three weeks to play the first turn. Too slow. Need instant gratification.
I was sure there were some people who played real-time, but I couldn't find that, so I've signed up for an every day game -- one turn per day, no press -- you've gotta guess what everyone else is doing :-)
Funnily enough, games like this are sometimes called 'nosleep' :-)
Mmm, just like when I've got an assignment due the next day: "Sleep is for the weak!" ;-)
