I played two games of Mr. Jack last night, which means I've knocked off another of BGG's Top 100.
Anyway, it's certainly a respectable little deduction/misdirection game. I'm not sure if it's the cream of the crop, but it's unique. And fast. Fast counts for a lot.
On the other hand, both games were strongly influenced by the order of the draw. When I was detective I quickly narrowed it down to two people ... The Yellow (guy) who controls the lights) and one other. But twice the yellow person moved at the end of the round under Jack's control, so there was no possible way to force Jack to reveal which character was the killer. I did win, but only because the last round turn order forced the killer to move prior to my characters.
Still, I don't mind luck in a 20 minute game. I think this falls into the "nice change of pace" category, and certainly worth trying. Does it have staying power? I don't know, and doubt I'll play enough to find out.
Update: As usual, I didn't really mention mechanics. I'm sure one of these reviews mentions them, but I haven't read any of them...
