Hello, this is just a suggestion, but I find that I work better when I'm doing it in the name of a Game Jam. Problem is, there aren't always game jams aplenty going on at any given time. To help alleviate some of this issue, I propose that either Scirra or a team of devoted fans (I'd be willing to be a founding member of the team if no one with more qualifications steps up) should consider hosting a monthly game jam blog.
For example, get a blog hosted, it can be blogger or wordpress for all I care, and create a Game Jam that repeats with a new theme or topic every month. Players then submit their games via Scirra Arcade link to the webmaster of the blog, who'll send them to the judges which'll grade the games and post a short writeup and review of each game.
Here are the categories that could be used for judging:
Sexiness (music, graphics, effects),
Transparency (clean, commented, grouped code),
Theme (How well does it fit the theme of the jam)
Post a "Final Results" page which has summarized scores and a list of all the games with their icons and a short 40 word description for each game, and done. Meet back at the same place next month and start over. Post an alert on the forums, have a twitter account to make announcements and feature the winners, whatever.
We could also perhaps make it a rule to share your .capx file and make some comments so that in the end, we can all learn from each other's creative mechanics.
What do you all think?
