A fun concept that requires a little buy-in from the players, as the random tables include behavioral traits for your PC. Most of the folks I play with would probably be hesitant to allow a roll to redefine the way their character acts or introduce a new jerk behavior to their PCs' esthetic between each mission. Too much of a risk to player agency.
It's a cool idea, with a lot of great entries on the tables. I'm likely to re-appropriate this for other purposes, though (maybe in a low-power Supers game with NPC roommates).
As an artifact, there's a LOT of black on one third of the trifold, front and back. Paper-texture-changing levels of black, depending on your printer this trifold isn't going to really sit flat. I'd run this through a grey filter before printing it. The back side of the trifold, when folded, includes the second half of a table started on another (not visible when folded) page, which is a bit sub-optimal.
I can easily see people having a lot of fun with this. It's not for me, but I'd call it more of a swing-and-a-ball than a swing-and-a-miss even in the context of my usual group. Definitely worth checking out!
