Maybe some of you have tried it but DEFCON is a lot of fun. RTS but not like StarCraft/CnC. Up to 6 players and basicly you nuke each other and try to loose the least amount of people. Alliances can be made, broken, reforged, whatever. My brother, my dad, and my friends used to play it every thursday night... until there was yelling and threats of assault. Good times.
