Review Detail of GREAT in Ultimate Simulation System

Ok, here's my review. If you're a fan of mechs, this should be your cup of tea. Magic? This should be your cup of tea too. And of course, it's a system book, that too. I'll try to create an intricate magic system then spice it up with enough mecha action, all you have to do is sit with a bag of popcorn, cold juice, read and have a great time.
