I have made a game with Adventure Maker. it's perfect to create something for fun. The soft is easy to use, has plenty of possibilities, but I would probably advise it for 1st person adventures, not 3rd person. I think it's easier to use than Visionaire. HOWEVER it is an old software now, and it has some limitations. The most important one is the resolution, which cannot go over 1024. Despite the restrictions, I still like this soft.
Visionaire is much complete however, and cheaper, and will allow 2.5D soon. I just think it takes more time to understand the logic of VS (how it works to create a game), the help system needs some improvement at this point (except for the community), and I find it a bit slow on some aspects (v3.7.1, let's see the next release). It's just an early opinion, I'm new with VS ! But it seems you have taken your decision to use Visionaire among others

Well done !
