Just three! And it may have been a Kay Bee that I got the supplements at...There were suppliments to Powers & Perils?!
I got that game on sale for $5 for the box set at K&K Toys when I was about 14. I still maintain that, on a "fun per dollar" scale, it was the best money I ever spent for an RPG. We played the heck out of that wacky, clunky system for most of a year.
There was Perilous Lands, which was actually a very neat setting with some adventure sites. It was kinda Eurasia-shaped, with a teensy Africa, and came with a puzzling map booklet instead of an actual map.
There was also Tower of the Lich King or something... I think it's crazy the only adventure released for the game was a high-level one, but what can ya do?

And really? You actually played it? I could never sell my friends on the system... I didn't think it looked bad back then.

FWIW, While googling around yesterday, I found that a dedicated group still plays the game. They've even errata'd the rules and put much of it online!

Oh, and speaking of Perilous Lands, here's the map.... (Very big file on a slow server)
