another idea would be if you play tourneys alot, you could run a series for a designated period of time (6 months, 1 year, etc.) playing a specific set number of matches and keep a leader board. There are sites out there that you can sign up for free that do this, you just plug in the info after every tourney. There are also simple point scoring systems that help to track standings, for example based on what place you get knocked out.
Aside from the usual tourney payouts, you could have a side till that builds over the course of the series for a grand prize the 1st place finisher could win, as well as an inexpensive replica world series of poker
type bracelet that I've seen online at sites before.
