Here is an idea worth considering, or so I think. What of badges for the Kongregate site as a whole? Here’s some examples:
Have__number of friends
Play__number of game each day
Log in __ number of days consecutively
Play for__ total minutes
Obtain__number easy(interchangeable with:medium, hard, impossible) badges
Post__number times in forums
Comment on number of games
Likenumber of games
I can think of many more to put on here as well.
Note:__ can be for example:10, 25, 50, 100(depending on badge requirements).
