Playing a second playthrough at the moment and I have hit the infamous "long loading times" -problem. So far everything I have tried has failed, so I may have to keep exiting to the main screen every time I want to re-enter Denerim or other crash prone zone. Or then the game simply doesn't like my polygamey -mod
And the game is easy even on Hard setting, since the AI is so terrible. You can wipe out pretty much any group by throwing in a few well placed AoE spells and by disabling the big foes with that bubble spell. Crushing prison and overpower are also totally OP against mages, who won't survive the effect.
Then again, if the AI had any teamwork, it wouldn't be an issue. Hopefully the mobs are a lot smarter in the sequel.
