It's still free for another day!!
http://www.gog.com/gamecard/torchlight www.gog.com/gamecard/torchlightI think this game is totally worth playing for free. It's a very "simple" and streamlined diablo clone. It's quite fun but of course extremely repetitive and kinda easy. Easy in terms of, you will always have so many health potions (you will end up selling 90% of what you find, because keeping like 4-5 full stacks of the best health potion is super easy to do) that no matter what a "boss" or whatever is throwing at you, you can just heal through it no problems.
Also, when I fought the last boss, it was so insantely dumb that I literally used 200 health potions and completely ran out. But when you die, the boss' life doesn't reset. So I would basically run in, nuke with everything I had until I died, respawn and run back in. It took like 15 minutes of this shit. So I wouldn't say it's a game you gotta play to the end or anything. It's fun enough to play for an hour or less at a time. There's also a secondary "cavern" that just goes on forever, and things will scale for a long time.
Only single-player though :\
