I'm playing on PC with a 360 controller and really enjoying it. The combat is well designed and is a satisfying mix between hack'n'slash and a tactical use of abilities. My main beef with Skyrim and Oblivion was that right-mouse block, left-mouse swing deal got old real fast. In most games that give you the warrior/rogue/mage option, I usually go for warrior first since it's usually the most straightforward to get a 'feel' for the game, but this time I'm going straight for
mage. Spells cost a lot of mana which discourages chain casting and promotes a more balanced battle-mage style.
Haven't really got far enough to comment on the story or quest quality, but so far it's all been quite engaging.
