Ogame iz funn
If you haven't heard about this or tried it I think you should. It's a strategical game about universal power. Register in one of the many universes and you'll start in a random section of a random galaxy in that universe. Build tons of structures, get a shitload of upgrades, research some crap, form aliances, build up a massive fleet, and control as much as possible.
It's kinda like a web-based RTS with MMO-like ideas. Fun stuff, give it a shot. The game operates in semi-real time so it takes a bit of patience.
