I wrote or edited the adventures, what, 17 years ago, and yeah, I feel a bit embarrassed by a lot of parts where I think now I could do better.
But I think as long as you involve the players in the setting so they care about the people imperiled by Ragesia, the adventures have plenty of fun elements where the PCs get to make their marks.
Adventure 5 is rather weak, though, I'll admit. I actually was working on some improvements of it here:
