Kinda odd to see this released for free, ad free and with no paid versions/licenses. I mean construct is opensource software so it's understandable but it appears stencyl was created and is being maintained by a private company so I wonder where they get their profit.
He's obviously building this into something big. There's no sense in limiting your appeal right out of the gate. He's gathering an audience first before he starts commercializing it.
And that kind of concerns me (full disclosure: I am paranoid, so everything concerns me

). Not that I don't think that tool developers deserve money, but YYG made Game Maker cheap and then started wanting 50% of revenue from iOS sales. Once again I think that the person/team behind Stencyl deserves money, but I'm not comfortable with them getting a dollar for every dollar I earn from my game as if the tool's contribution is half the value. And even if you do think that the tool used to make a game is worth as much as the design, code, art, levels, etc, does one company deserve to get half the profits off of hundreds or thousands of games (depending on how popular it becomes) that use that tool? As always, I am asking from an ethical frame of mind, not a legal one.
I'm always cautious of these types of deals, especially when the license agreement can change any time they want, such as when they have a large portion of the indie dev community using their tools and competing with each other. Anyone know the ethics of the team behind this tool? Maybe a good track record of indie involvement or open source development or saving sick abandoned puppies could ease my mind
