Here's a game that can be easily converted for really anything. First print out the letters (about 1 set of letters for every 2-4 players), laminate, then cut the letters out. Then hide them around a designated area. Then give everyone a bag to collect the letters. When all the letters have been found, then have each "team" make up as many words using the letters they collected, using the letters only once.
And here's the scoring:
7+ letters = 10 points
6 letters = 8 points
5 letters = 6 points
4 letters = 4 points
3 letters = 2 points
2 letters = 1 point
1 letter = 0 points
If letters aren't used -1 point for each
