So, I'm a relatively experienced GM, and I've moved recently to a new town. I've started up a group with some of my new friends, and my brother and I are the only two with any Roleplaying experience.

My brother is a great guy, but he Munchkins and min-maxes and abuses loopholes and only plays tier 1 spellcasters like Wizard or Cleric. Rather than force him to make a subpar character, I came up with the idea seconds ago to make him play an Adept. He can do whatever he wants with it, it just has to be an Adept.

I'm hoping this'll keep him at the same level as all the unoptimised characters everyone else is making, which appears to be mostly barbarians and other 'sword' people. I'm aware that there are some landmines present if I do this, however.

Do you guys think I should suggest this to him? What are some things I should consider first?
