I don’t the idea that’s it an MVP award. It implies you’re voting for the best player on the team. Limiting the number of votes you can give/receive a day reinforces this. A simply up voting system would encourage polite behavior. If I had a pleasant run, I would want to up vote everyone in the party. Are we trying to encourage excellent play or well mannered behaviour in the player base?

Rewarding players with “Item Mall” type items won’t make for a lasting incentive and puts a burden to the dev team to continuously be adding more items The idea thrown out there by Moheeheeko that points could be used for repairs is worth looking at. Trading them for company seals, expendables is something people could have value. Having the total points players have accumulated be visible on their profile will create social pressure for them to play nice with others.
