Which RPG? (Score 4, Interesting)

I read some time ago that, at a convention, you had admitted that The Tick started out as a character in a Superhero Role Playing Game. Of course, they failed to say (or perhaps you didn't tell them) which game! So which was it? Champions? V&V? Superworld? Marvel Super Heroes? Do any of the other "standard" Tick Universe characters come from the game? Do you still play?
