Shacknews reports the Torchlight 2 demo is available.
You can download the 1.3GB demo from Shacknews, which is really the full client you can later unlock by buying TL2 direct from Runic, or through Steam. Heck, why not download Matt Uelmen's lovely free soundtracktoo?Why not give it a go? You've got nothing to lose. If you're a fan of Diablo, I highly recommend you check out Torchlight.
