I think our main contenders - all of which you missed! - are Game Maker, GameSalad, Multimedia Fusion, Unity3D and possibly Stencyl. I don't mind discussion of alternatives as long as it's not bashing or trolling. I also think Construct is (and C2 will be) the best out there, so I'm not afraid everyone's going to disappear just because they find out about an alternative!
I'd guess most people are on this forum because they already prefer Construct. So perhaps you could rephrase the post - instead of just a list of alternatives, how about something like a comparison to Construct, or something along those lines which might be more relevant to users of this forum?
