GURPS

GURPS, aka the Gaming Universal Roleplay System!

Has a reputation for being complex, but that is because you have the ability to make pretty much ANYTHING! The U does stand for UNIVERSAL after all.

So go ahead and make yourself a GURPS character. The only thing stopping you is your imagination!

Or don’t, I’m not your boss.
