Atomic Robo: The Roleplaying Game. But I think I've seen plenty of that thus far, and besides, I have to write up a number of characters from Robo canon anyway.
And you know what? It was a lot of fun. '30s Robo, Jack Tarot, and Helen in particular, because it gave me an excuse to pore over The Deadly Art of Science. Of the other two characters, one's based on Welles' character in his War of the Worlds radio drama, and the other's wholly invented but a plausible participant in the events of the scenario. (I also enjoyed finding character portraits, which is something I rarely do.) Regardless, they all look fun to play. Here's hoping I'm right about that, eh? Guess we'll find out tomorrow at Dice House Games!
So here they are. If you're in the playtest, check it out! More characters ready-made for you! If you're not, then check it out! Here's what characters look like!
