Monkey Island series is apparently doing well on Steam. The distribution platform's sales chart shows that the first season pre-order of Mr. Threepwood's latest adventure was the top selling game "by revenue" for the week.
Rounding out the top three sales spots on the service are Street Fighter IV and Fallout 3. If you're sitting on the fence -- made out of the boats LeChuck has sunk -- about purchasing the game, check out our review or the demo first. If you don't own a PC, the Wii version is en route and an Xbox 360 version may be available "later on."
