AtWar
It is called AtWar, it is like a world map and you choose a country. Then you start to take over the world, even you can make alliance with other players or declare war at them. Just don't let them betray you. Even you can buy upgrades with points to get new units or stragety. It adds a twist to the game and it looks quite balance to me (aside the premium players.)
I played as China and other player played as India. He took my capital city and I counterattacked him with my tanks then I proceed to take his capital city and took him down. It was hiliarous when other 3 players form alliance against me but I still took all of them down.
It has to be one of the best MMO conquest game I've played, others I played sucks.
