Gotta totally disagree with you there. There were significant consequences from choices you made as a player, with decent skill customisation and well written dialogue. The main story arc was decent and many side quests were nicely designed. So as an RPG, it was superb.
Combat was fine too. I played on Blood and Bones difficulty and learned very quickly not to make too many mistakes. Combat was intuitive to me and was pretty fun. Or maybe I'm just a dexterous genius. Or a masochist.
The game has won more awards than any other game out there. Maybe it really is good?
