There are some nitpicks- skills are rather poorly explained, and it's hard to respec if you screw up a build because of this. Bosses have huge collision areas while the hitboxes on the small fry are tiny, meaning you can easily mis-click when you attack regular enemies and generally end up always attacking bosses in packs. These are small complaints- the core game is tremendously solid with responsive controls and immense stability. If you were let down by Diablo III or even Torchlight 1, give this a shot and you probably won't be disappointed.
-More classes, better enchanting/socketing, nicer graphics, bigger areas than Torchlight 1
-Unlike certain other ARPGS, cannot be beaten in 2 hours by a sneaky player ;)
-Immense build customization encourages repeated playthroughs
-Multiplayer comes to Torchlight!
-Cheap! (Unless you import the German DVD release, heh)
-Unclear skill descriptions + limited respecs = frustration
-Builds dependent on high-level skills can be VERY frustrating at first
-Randomly rolled spellbooks and enchanters can make the early game very hard or easy based on luck
