I'm a GURPS fanboy. Complexity is determined entirely by how many rules the GM and players agree to - I've got a player with dozens of skills and several wonky abilities who plays side by side with an 8-skill player. They both do well, and both have what they want - one character is just more detailed than the other.

The trick with GURPS is to pull in the bare minimum of rules that you need for the kind of game you want. If you don't like how a rule works? Swap it out!

I've enjoyed the Ironsworn line too, for a different feel. That's a much less complicated system that can also be played GM-less, it works narrative elements into the engine - the story dictates how the rules apply!
