A recent YouTube documentary (embedded below) on the history of this game reminded me just how awesome it was. While its not my all-time favorite RTS game, its certainly up there, and I now have a strong desire to replay the campaign. Luckily the game is available digitally over at GOG. If you never played World in Conflict before you should check it out. The game focuses on unit tactics. There is no base building or resource gathering. You have a set amount of credits to purchase units that are air dropped into battle, and when units die their cost is recycled back into your pool so you can buy more units. There is a lot more to it, of course, including a pretty unique class based multiplayer setup.
