Sadly what you said in that topic didn't really reassure me.
Obviously, you are motivated to do better than clickteam or yoyo games did with their products, but I don't see how you are planning to do it.
Since the competition is already well established in the market, I'd say 99% of your customers are going to be previous mmf or game maker users, so you really need something to motivate them to abandon their software of choice and choose c2 instead.
Until now I haven't heard of a single feature that the competition doesn't have, let alone one that would make it stand out.
If it's going to be better than mmf or game maker is very subjective and unpredictable since we don't know how they are going to be by the time construct 2's 1.0 version is released.
My suggestion would be to follow yoyo games's example, and go with a free and a paid version. It worked for them so in theory it should work for you two I think. When I mean free version I don't mean construct 0.xx I mean a solid product with a few features cut from the "pro" version for example and/or forcing a non-commercial license.
