Can't really speak to the adventure creation as I haven't tried that part quite yet. So far, I like the tool and am glad for the purchase.
Two negatives:
1) The user manual (while extensive at over 100 pages) is not as instructive as it could be. This is purely IMHO and YMMV. What I haven't been able to find in the manual I have found in their forums, so no real big deal.
2) This bad boy is a resource HOG. Even after I verified that my software settings were as recommended, the thing is just slow and the rest of my machine comes almost completely to a standstill.
Having said that, I don't want this to be perceived as a negative review. Once you get your hands around the product, it can do some really beautiful things and make even the artistically uninclined among us look good
