I bought Torchlight a couple years ago because I needed a cheap entertaining game that didn't take a lot of compute power on my laptop while visiting family. It was a blatant ripoff of Diablo 2, but it was very good mindless fun. I understand a sequel came out but I didn't play it.
I played the Diablo 3 beta over the weekend and I wasn't really blown away at all. Sure it was mindless fun, but outside of some physics upgrades like chandeliers crashing on enemies and falling walls burying undead stuff, how has the series advanced? I remember very little difference from the original Torchlight.
My hope for Diablo 3 is that the clamped-down security with Battle.net will filter out the cheating, botting and general thuggishness I encountered when playing Diablo 2.
