Quick note: was looking at Game Maker Studio 2 earlier. The free version seems to be even more limited than the free version of VS because not only does it limit you to x rooms/scenes, it also limits the amount of objects, scripts & other things you are allowed to create & a lot of advance features such as shaders are also disabled as is exporting.
The freeware version of Visionaire Studio is exactly the same as the paid versions minus exporting & the 10 scene limit.
I know other engines like UDK (unreal) & Unity are free, but even those are only free to a degree based on what you develop with it & whether or not you make over x money or need to purchase modules for one reason or another or want to export for some platform that isn't included in the free version. So yes, we could argue both sides of the field on whether limitations are a good or bad thing, but I don't see 10 scenes as a massive issue - still, I would like to see export options for windows, mac, linux & html5 so that people can export working technical demos of their games to share with reviewers, bloggers & for kickstarter campaigns & competitions & so on.
By the way, it's possible to make a feature length game with around 20 scenes (maybe less) so I think 10 is a decent limitation & even that is generous in a way as you could easily make an episodic content based game with 10 scenes or less per episode.
