Julmust, thanks for the feedback.
Essentially, the goal is to one day pay out based on ad revenue, but this isn't feasible at launch. Additionally, the Scirra Arcade which is useful in its own right doesn't exactly court gamers who aren't involved with C2.
The goal is to create a showcase, a springboard for super small and new developers, not the next Kongregate. The final site will function like a blog, showing off new games, instantly playable from within the website.
