Not sure if this will catch on, but as an experiment, I thought up a 2010 game for our top 80 peakbaggers in 2009. Eight teams of ten, assigned so that group totals are evenly matched, and members are not likely to hike with each other. The goal? To climb the most distinct new ranked peaks as a team (it benefits team members not to hike with each other because a peak can only count once for the team). Designed to encourage members to try something new in terms of summit selection.
Attached is the team assignment.
Here is a summary with drilldown from team down to members down to summits completed:

Team names and logos, google maps with color markers corresponding to members in a team, etc could make things more entertaining.
