You should definitely play it
Torchlight II is still chugging along, and this weekend, you can play it for free on Steam. Said free weekend starts now, and ends on Sunday at 1PM Pacific. I never really got all that into Torchlight II, but it's a really great game, and any dungeon crawler fan owes it to themselves to try it.
Give it a go this weekend, and if you enjoy it, at least grab it on a Steam sale -- you won't regret it. Like, you know, this sale this weekend, where it's 75% off.
