I don't play zone yet, but I think the "jobs" should stay strictly theme specific. No "car" missions.
1.) Racing. Some kind of bike or car race. Make it into a league where you race for gralats.
2.) Never-ending Conflict. This is exactly like the pirate update on classic, but with a twist. Maybe a war has broken out on a planet and the player has to "survive." maybe you have to get a specific amount of kills to achieve your goal. If you die first, you are paid for number of kills. The NPCs could be robots, aliens, monsters... Whatever you like. Something more challenging to face besides pking another player.
