I searched for 10 minutes and couldn't find anything similar, so I apologize if this idea has been offered forward before.
Concise description: Silver and Bronze Tournament medals given out for placing 2nd or 3rd in a non-standard, overly-large tournament.
Specifics: Off the top of my head, I've participated in two such tournaments, Blitz's Battle of Annihilation Tournament, and Lindax's TLO 2009 II Tournament. However, the Map Blasters tournament currently under way, which I'm not apart of, comes to mind as well.
With Tournament Mod approval, long, marathon tournaments where players play 50+ (75+?, 100+?) games could offer Silver and Bronze tournament medals.
It would be the same shape as the current tournament medal, and the same silver and bronze colors that are offered with the other medals, so I think they'd be fairly easy to create.
This will improve the following aspects of the site: It seems to me that many tournaments created are small, rather undeserving tournaments where the sole purpose is for the host to acquire a Tournament Contribution medal. I think that this setup would encourage the creation of and participation in larger, more "real" tournaments.
I apologize if it seems like I'm trying to reward mediocrity. That's not my intention. I was listening to Olympics coverage on the radio and moving in a TLO game, and the thought occured to me.
