Today marks the official launch of Torchlight, a single-player action RPG that will ultimately be followed by a free-to-play MMO. Diablo fans may want to check out the game since development is headed by a team that previously worked on Diablo, Diablo II, Fate, and the unfinished Mythos.

The game costs $19.99 and is available for digital download via the official site, Perfect World, Steam and other sites. You can find a list of all the partners here. Also, the level editor should be available as a free download on the Torchlight site later this week.
