Wandering Adventure Party

Maybe try GURPS + Supers suplement?

The main problem with magic in Mage is that you need a LOT of rule knowledge to even know what the fuck you can cast, especially if you mix different spheres. Your friend might’ve dodged a bullet, but for the wrong reason

I personally prefer Warhammer Fantasy (either 2e or 4e), I think it contrasts to DnD like Dark Souls to Diablo. Armor is damage reduction instead of damage avoidance, everyone has access to a number of combat maneuvers, magic is limited and dangerous, every combat is dangerous and healing is limited.
