10. Torchlight II (Runic Games, 2012)
There are quite a few Diablo-styled action dungeon crawlers on the PC, but the one that takes the genre to perfection in my book is Torchlight II. Created by a team partly made up of former Blizzard North (Diablo I) staff, Torchlight 2 takes everything that made Diablo a hit and cranks it up to eleven. Combat is fast and frantic, the four playable classes in the game can be customized in any way the player wishes, and online multiplayer (sorely missing from the first game) is now back in full force. The game even has full support for player mods which can even be used in online games, though all players must have the same set of mods installed in order to play together. Some other clever tweaks, like each player finding separate loot drops and being able to send your pet back to town with a haul of items to trade in for cash or potions, also make sure that the action remains constant throughout. Torchlight II is pure fun.
