I'm not sure if anyone has played this, but it's called Defcon. It's a real-time strategy that takes place on current-day Earth, I guess. Each player is positioned on a random set of countries/continents depending on how many players are in the game (this is pretty much what makes the game the most fun). You build fleets of submarines, battleships, carriers, etc. You also build airstrips, radar towers, and stuff. Eventually you can put bombers and fighter jets in the air, as well as launch ICBMs and Nukes at Defcon 1. You get points for destroying enemy units and buildings but also get points for bombing enemy cities. It feels pretty rad to bomb a city and have it say "Barcelona hit... 1.5 Mil. dead."
Anyways, it's free if you don't mind only doing 1v1 online, or single-player. I've been playing it every night for the past few days while going to sleep. lol.
