I think Zone should have its own Spar Tourney it could be held monthly or so, and the prize could consist of something nice, not just grenades, or maybe a large quantity of Grenades, and money?
Besides, a nice prize the winner will also have his/her self embedded as statue on the Spar World, for the time span he/she won until the next Spar Tourney (Scheduled one, random ones don't count).
Note about Spar Statue: It would be capable of copying an account's look currently online, it would work with a simple command, "/setsparstatue <account> : Sets the Spar Statue's outfit to the account specified".
