Recently, Matthew posted a wonderful list attempting to categorize different types, mechanisms and themes found in games. You can read it here:

My question for all of you is, what order do you typically choose them in when you design a game?
Do you create mechanics first, then wrap a theme around it?
Do you come up with a theme for a game you'd like to make, then create the mechanics?
What do you think are the pros and cons of your approach (or other approaches).
I tend to switch back and forth between them, but more often I create the mechanics then wrap a theme around it.
You hit the nail on the head for me. That's exactly what happens for the majority of the games I have designed (not that there are that many yet). I will on rare occasion get an idea for a mechanic, but usually the theme comes first and I then set about finding the mechanics to support it.
