I don't know why people claim GDevelop is an alternative, it simply isn't in the league. And unless my memory is faulty, Stencyl isn't up there either. So why are they being mentioned?
GameMaker would be (personally I don't like that company-but anyway), or the next version of Clickteam, but why are people suggesting a step backwards as an alternative.
(Btw: I'm not a fan of the change [I do understand it though] - and won't buy C3, but lets not pub talk these topics)
