Indeed, as Thomas mentioned above: The demo game competition is being held to provide a new demo game (template) which will let people see how a game could be made with Visionaire Studio 4.x. With the demo games I will have access to assets/resources which I could use to create tutorials from. I am not an artist, I possess very limited artistic skills & zero 3D skills. I tend to focus more on scripting, development, thinking (brainstorming ideas & solutions to problems), etc.
In regards to the money: there isn't a continuous stream of buyers each day, week or month, so the few sales here & there most of which will be the indie individual license) after paypal fees/tax or whatever doesn't really amount to much. Visionaire Studio isn't a massive commercial engine like unity, or udk. It doesn't have a massive team of people working on it day & night - or 9 to 5. There are currently 3 devs who devote most of their spare time to the development & improvement of the engine, myself (providing support on the forum & documentation on the wiki, when I can) & then there's Thomas & Calli who are working on the website/cms & other web related things.
Finally, in regards to the 3D support: the 3D system is still in the early stages, it was only added to the engine recently & is still pretty raw. Also none of the devs are particularly 3D savvy, but lots of people kept asking for 3D character support, thus it got coded & integrated into the engine by one of the devs more 3D savvy friends. & then everyone complained because it was buggy. but as I said it's early stages for that & I'm sure it will improve over time & each new release. Can't expect everything to work perfectly off the bat, each run.
Also I am not sure who will be providing documentation or tutorials for the 3D stuff as I have no clue at all about how it works, nor do I even know where to begin when it comes to creating 3D models.
Akçay Karaazmak spent some time trying to figure out the best approach for creating 3D models & which formats etc worked best in VS. His findings & notes are available in the FAQ section of the wiki @
