My main gripes are that it's too much zoomed in, even at the max distance, and the inventory. I don't understand why it has to be so goddamn small.
Other than that I'm enjoying the game. I've never seen an ARPG where I felt more involved in the quests and story than this one, and that says alot because this one is nothing to write home about. But how multiple NPC's in a town recognize your accomplishment of a single quest completion is something new, and I like it. Why should only Person A recognize I killed this monster who made everyone's life miserable and not Person B and C as well? Good touch right there.
I also love the potion system. It has a special kinda dynamic of its own. I think it's really well balanced.
Last but not least... those chained women at my health and mana orbs, wow. Gotta trigger every straight guy's imagination.
