I've toyed with doing an "easy game maker" but have always ended up leaning towards making high-powered "real" tools (whatever those are) instead. My current goal is to make a game IDE that resembles a Smalltalk or perhaps Emacs-esque system - highly reflective, image-based, extensible, but more specifically game-focused, with the core features and main loop hardcoded, but everything else being part of the same system. The current state of the art in these tools(Game Maker, Unity, UDK) tends to stop just a little bit short of this "build tool and game very closely together" idea, but the way I see it, that's nearly the last major win for iteration times, within our current understanding of the development proces.
