Ok, first impressions : good performance, good looks, no openness at all (you can't swim or climb), the combat system doesn't really seem particularly impressive so far, I wish the interface didn't look so console-ish (though I have seen worse) and there are far too many untargetable villagers that also don't react when I take out my weapons on enter their houses.
Still, it seems to have the potential to be a decent game, and I definitely like the multitude of options they put in their options menu.
I'll play the demo more but this looks like 'wait for its price to drop' material so far.
