MechForce has a level, mission and mech editor. I made a bunch of missions (custom and random maps) that makes this good strategy game much better. It's best played with friends playing multiplayer (4 player adapter not required).
AerialRacers is another fun multiplayer game with a track editor. Gravity can be edited also which is interesting.
