If this haven't been suggested already, I will be very disappointed. SPARROW-EFFIN-RACES! It could work just like the Vanguard and etc. You would gain reputation and marks doing races, upgrading your 'race sparrow,' buy/win race shaders and overall have an awesome time racing each other! Races: You would have to buy yourself into a race with either glimmer or race marks, allowing the game to create a winner roll. Players can spectate races and bet glimmer on their while keeping track of upcoming tracksters on the race leaderboards. So, how about it, Bungie?
