I used to sneer at such tools, considering them "not real gamedev". That was until, on one local edition of Global Game Jam, a designer in our team did in Construct in 15 minutes what took three of us coders a couple hours. This drove home the point that we were really overcomplicating things by coding a simple game from scratch (in XNA, back then).
