Crosmando: I just hope the spell effects aren't too *bright*, it's one thing from Neverwinter Nights 2 and other RPGs that annoys me. I liked how the IE games were quite minimalistic on spell effects, "mundane" even if you will.
I hope it's somewhere in between, not too flashy not too muted. Hope buffs don't transform you into a glowing ball of light which hurts your eyes. I don't mind the higher level spells to be a little "epic" looking if possible, of course not too flashy or exaggerated.
FoxySage: I liked NwN 1's spell efffects. They were flashy enough to make you feel like a powerful caster in the game. (even if the Hellball was a bit anticlimactic since you could easily dodge all the damage from the epic spell)
I liked NWN2's Greater Missile Storm, and of course I kept spamming it with a Sorc. lol
