6 player LAN party game of age of empires 2. It took 8 hours to play. Very very close game. At the end, 2 players left -- massive battle -- awesome.
We were doing things like mutually agreeing to pause the game so we could go and have 'war meetings' to discuss strategy without the opposition hearing (as when we were playing we were all in the same room.
And yes, it's nerdy. And yes, I don't care. Awesome, awesome Sunday. The game was soooo close it was just bizarre!
