I'll trade you either a Steam key for "Cortex Command", or a copy of "The Ship", for Torchlight 2.
Thousands of copies of Dirt Showdown were given away for free at Comic Con over the summer, that's the only reason I was making any sort of comparison. The supply of TW2 was much more limited than what Dirt Showdown was. If you're not interested, sorry for wasting your time.
I won't give an exact value because I haven't done the math myself, honestly more than TW2:VE, like I was offering (to the OP, it was more of just taking a shot, can't hurt, right :P), but I've seen keys go from $8-$10 like 2-3 months ago, haven't kept track of it much since then, the price has most likely gone up by now since most of the keys were probably used.
Interested in Torchlight 2, check my list please, I'll trade several games for it
