Looking at gathering storms and wind of magic: it looks to me as if some of the fights seem very tough for a beginner party.
In gathering storms, the goblin final fight in particular looks delicate to say the least . With about 2 regular gobo per player plus the shaman, I don't see how the PC can survive unless you play the shaman as an idiot (or your whole group is composed of waywatchers/two weapon fighting/great weapon killing machines).
In Wind of magic the "introduction" scenario is a bit over the top: the big demon seems ridiculous in power for beginner (and has 8 smaller demons and half a dozen cultists/mutants with him).
