1. the combat system is actually a pleasant surprise for me. yes its primarily clicking the left mouse button. but what i noticed is distance has an effect on enemy spells where you can avoid them. also the dodge feature is very handy, i find myself trying to evade enemy attacks and judging distance to monsters quite frequently. its not as tactical as a turn based (which would bore me to death) but its tactical enough to not just be a simple diablo/titanquest clickfest (which i wouldnt mind that much actually). to sum it up i find combat fun (im a melee mage).
3. focus on story is pretty much as it is in all these types of games now (fallout, kotor, mass effect, gothic) it has an interesting dynamic, but it is standard fantasy fare. theres a lot of dialogue if thats what you're wondering.
