Torchlight 2 has got to be hands down my favorite ARPG Hack and Slash game, and in my opinion the best ARPGHnS game of all time. The modding capabilities are extreme, and the extent to which you can "break the game" in terms of insanely high DPS, extremely powerful item and ability combinations, and the sheer amount of stuff you can do. In addition to all that, the amount of mods that people have developed is insane. If you're looking to mod this game, I highly recommend the Synergies mod, Hack n' Slash essentials, Thrasher's Armory, LAO2.0, LAO2.0(High Drop addon), and others. However, if you use them, do NOT use Extra Chunky, it'll crash the game upon loading, although you won't lose any data or characters due to crashing this way, unless it shuts your PC/Mac down, in which case I have no idea what happens. Anyway, great game, makes for really good multiplayer campaigning. One thing though, there doesn't appear to be a way for modded multiplayer campaigning.
