While this theme may initially seem very restricting, you've got a lot of wiggle room and can play around with the format.

For instance, instead of comparing and contrasting different mechanics from different games, I could take just one mechanic I've frequently seen -- let's say, Quick Time Events -- and discuss how that mechanic has been used really well in some games, but pretty poorly in others before analyzing why. So long as you're doing some sort of comparison/contrast between game mechanics which are related in some way, you're fine.

You can start writing theme-related community blogs now, and we'll be accepting (and hopefully posting) submissions until the end of the month. Apart from the requirement that you follow the theme, there really aren't too many ground rules for the Monthly Musings: just be sure to title your cblog "Good Idea, Bad Idea: _________" and you're fine.

Be as creative, angry, or analytical as you wanna be; the goal here is to start discussion of any sort. Get some interesting debate going, and you'll be promoted to the front page.

 Any questions? Ideas? Hit the comments. Otherwise, make with the musings.
