Many real-time strategy games now have multiplayer options that allow you to wage war over the Internet. In most cases you are required to gather resources, research new technology, build up an army, and use it to vanquish your enemy. The player limit is typically between 6 and 12. A game's popularity is not the only consideration, and these selections are based in part on my opinion and your feedback. Feel free to let me know if I've missed something.

Warcraft 3

This game is the latest installment of Blizzard's award-winning Warcraft real-time strategy series. Although it was released in 2002, it's still one of the most widely played RTS games in pro competitions. The Battle Chest version includes the original, Reign of Chaos, and the first expansion, Frozen Throne. Features include 3D graphics, compelling new roleplaying elements, and expanded multiplayer options for up to 12 players over Battle.net.
