in search of a ranking system

One of the next things to be added to Lux is an online leader board. So that of all the humans who are playing each other online they can each be given a ranking. The only thing I have to do is come up with a nifty algorithm for determining the rankings. I was looking around today at chess ranking systems, but didn't really find any good descriptions that fit my needs.

Each player will not have played the same number of games as each other, which kills of a bunch of possible systems. Anyone got anything to suggest? Right now my brain hurts.

PS: Pickup ultimate frisbee today and every tuesday at 6pm on the McGill lower field if you didn't know.

Use a ladder system. You don't need anything complex.

Give everyone a rating of like 1500, and then for every game that is played, increase the winners rating by a value and decrease the losers rating by the same.

The amount that each score changes can be tricky... You should have it that if a good player plays a crap player and wins, his score goes up by pennies, but if the bad player wins then his score goes up alot.

getit?
