This isn't an ARPG, but there are games entirely devoted to killing monsters to upgrade your equipment so you can kill more monsters to upgrade your equipment. In D:OS, and the earlier Divinity games, equipment upgrades are part of developing your character.
Yes I know, but currently it feels like one.
What I mean is, how can a sword do 10-20 damage and a few hours in you'll find weapons that do 90-160? Logic is lost here.
Even if you find something good, Esmeralda will always have something better. And this bugs me.
