I haven't had much time for gaming recently, for obvious reasons, however I have been fascinated by a game called World in Conflict for quite a while now, so I downloaded the demo a few weeks ago.
The demo consists of a tutorial (needed), the first level of the single player campaign (about 1 hour play time) and limited access to some multiplayer online action.
I haven't tried the multiplayer yet, but I loved the tutorial and Level 1. I just wish I had time to play the rest of the game! I won't be buying it as I can't dedicate the time any more to playing, but I can highly recommend that you check out the demo.
