Mythos met a sad end when Flagship Studios went down, but the newly reformed Runic Games brings a lot of those developers over and they're hard at work on a new online game called Torchlight.
This lighter, casual game, will kick off later this year as a single-player experience, before expanding into an MMO.
This new game is, like Mythos before it, aimed at a far more casual audience. Prior to Mythos, many of the developers also worked on Diablo. Naturally, Torchlight is an action/adventure RPG.
