Try 4th Edition, I am having sooooo much fun! But if you want Spells to feel like more than just different flavors of damage/buffs/debuffs, I would recommend the addon “Magic - Deeper Secrets” that brings back a whole lot of the extremely creative spells from 2nd Edition.
I never had a chance to try Earthdawn, but it looked like a lot of fun.
