I wished this game had been purely devoted to the Unisystem, but D20 has its hold on it. This basically means the majority of the book is useless to me.
I'm still giving it a strong rating because the concept of the game is terrific.
You travel alternate dimensions
You have two characters in the games.
Also, I find the paperwork required at the game's end to be great. Make your players fill it out alone so they can't get their stories straight. You can then hose them for lying to their superiors! Trust me . . . this is wicked fun.
