I'd actually heard of the first two games in the series before Demon's Crest was released on the SNES. Interestingly enough, the series started on the original Game Boy with Gargoyle's Quest. Gargoyle's Quest II got released on the NES.
I was wondering if anyone was into this series. I think my friend owns all three games. He let me borrow his copy of Demon's Crest some time ago and I really enjoyed it. Good action/platformer with RPG elements. Been trying to find a copy ever since but no luck. Demon's Crest is the only game in the series I've played.
