All right, so I've tested the Mastermind Maker a bit

It's pretty solid, but I do have a couple of complaints

1. When I import .por files to the Mastermind Maker, there's this weird glitch where I can't bring down any of the abilities/skills/defenses because I assume the system believes it's still at 0 because it's a new sheet despite it being imported

2. I really don't like how it doesn't auto-calculate the Power Level the way it does in Hero Lab whenever I tweak attacks. I actually really liked that because it helped gauged what I'm dealing with

3. I don't like how I can't have the Power Profiles and the Gadget Guides at the same time as some of the other supplements. That feels very limiting, and I don't know why

I hope they fix these up in future patches. That aside, it's pretty cool, and I'm glad I have an up-to-date 3e character creator.
