In The Phantom Menace, Qui-Gon enters little Anakin into a Pod race, and gambles if he wins, he will be free'd. Now I have played a lot of different MMORPG's, from WoW to Guild Wars, and a lot of other little indie ones, and a lot of them have certain "events" for a holiday or certain month, and I thought it'd be cool to introduce Pod Racing to a PvP war-zone. Start it out as an event, and if it's successful, make it into a permanent thing. Guild Wars has an event similar to this idea in a way, and it's beetle racing, you get to customize your own beetle design and everything, but it only happens a certain time of year.
I also thought it'd be interesting if you could customize your own bike for that. Now since most gear pieces are usually set in stone with color and features, besides the orange pieces for the modification pieces you can change out, it'd be awesome if you could customize the colors or the designs on the side. Maybe you can buy certain pieces for bikes through Warzone Commendations, or make into a Schematic for Cybertech or something. Just a thought, I'm sure it'd be pretty BA if it would actually take a hit.
