Max shaefer, the president and cofoundator of Runic Games announced that Torchlight 3 will be released before Diablo 3. He obviously was joking about the game politic of Blizzard.
But what about Torchlight 2 ?
It's intresting to know that Runic Games listened the wishes of many players wich is to see cooperation mode in Torchligh II. And it seems that it's gonna be great ! More classes, more game play multiplayer and a lot more !
The only thing is that we have to wait until this summer.
