Looking for anything with mouse control like Diablo that are not standard hack and slash games.

I like the mouse control and combat of Diablo-likes but I always get bored of going room to room and deleting enemies.

Some examples of what I am looking for is the Dungeon Siege and the Sacred series. Similar control scheme and combat but they are more open world, more involved side quests and more traditional role playing elements like Strength, Endurance etc. Basically just something more to do than killing and going in one direction.

I don't mind old graphics (in fact I prefer it), jank, very niche games or very simple systems. I just like roaming around with a minimap and finishing side quests using my mouse.
