What's the point of making Construct 3 other than finding a way to charge people again for the same product?
People say that C2 is easy to pirate - so I believe that C3 is essencially C2 with more control from Scirra.
I think that C3 is good for its creators only. To me (and all users I've talked to) it was completely unnecessary to make a new Construct instead of putting all these new features on existing C2 engine.
I completely understand their move from a business perspective (make a safer version of the engine to avoid losing money). But it sounds ridiculous to make C2 users pay for other people mistakes. "Other people" in this case are the dishonest pirates and Scirra themselves (for creating something that wasn't secure enough for them).
They already did something similar when Construct Classic was abandoned in favor of C2 (for obvious reasons - CC is 100% free and some years later they probably regretted this). Now I wonder how long will it take to Construct 2 forums will be in read-only mode (like CC forums already are).
