It would be similar to Zynga, with a few major differences. Zynga games can be created/edited by experienced developers. i want to create the basic framework, and libraries and just have wizards and online creation so a 10 yr old can make his own game.
I planned on targeting a more mainstream audience with respect to game creation. Simple tools, but robust design features, as well as an extensive library of props can go a long way.
Zynga is much more in the Kongregate/Newground space, serving as a hosting & distribution service for Flash games made by experienced developers. This guy (and us) are targeting programming novices who want to create their own games without programming experience.
