Post monster ate my post. (Whenever that happens here I curse the gods and promise myself I won't ever try to post again. It doesn't last long, though, and Craig deserves the review.)
I give it 4 stars for the module (good mix of combat/RP, good pace, interesting locales), 4 stars for our GM (would've been 5 stars but he was a little late, and needed to build some NPCs; it worked out because I helped some new MapTool users in parallel), and 5 stars for our platform (MapTool and Vent worked great, although Windows did have a technical glitch for our GM).
The module was combat, RP, RP, combat/stealth, RP, combat, RP. We did the "stealth" thing when a frontal assault would probably have been just as effective. But we were a bunch of newbies (bard1, rog1, monk1, wiz2, wiz4) and without a cleric or meatshield we were trying to be careful. :)
As you can see though, a good mix in the module of combat and RP. We picked up on a couple of things that smoothed the way for us, and the GM did a great job of keeping things moving as well.
It's certainly worth the $4, although I don't know if the graphics were easily used in MapTool or whether some work was required on the GM's part.
