I just thought that potential uDG entrants may want to take a look at this article I wrote earlier in the year about some of the potential pitfalls the novice (and not so novice) game developer can fall into.

From Little Acorns or Taking Development a Step at a Time

It covers development as well as design but I could not find a particular forum here to post it in so feel free to move it to where it should go.

Great article. I read it when you first posted it, but a re-reading was definitely in order. Thanks for reminding me!
