I borrowed a 360 controller from my brother and the game is actually much more fun now, whereas before I would quit after playing very long, even with a lot of rebinding and experimentation. KBM is somewhat serviceable as a mage or archer, if you like melee, forget it.
After playing with the controller, almost every single aspect of the game is easier, from inventory (Probably the biggest difference, incredibly more fluid with controller), camera manipulation, party selection, looting, combat, on and on. The only things that are better with KBM are the war table and the connect the dot astronomy thing lol! Both of which is inconsequential.
Oh and quick saving. I'm not aware if a way to quick save with the controller, but its pretty minor. I usually quick save like crazy in games like this. Manually saving is quite fast with a controller though.
It's clear the entire game is built around a controller scheme. It is not an opinion like some have suggested.
Overall, I'm pissed that the PC controls and tac-camera are so clunky, but besides those two (admittedly huge) things, this is everything I wanted in a new DA game.
I definitely feel the pain of those without access to a controller. I could afford to buy one, but refused on principle, and would have shelved the game until a patch or mod came out had my brother not loaned me his controller. And since this game is supposedly extremely difficult to mod and no info has been released about a patch, it would be a long wait.
