I just in game generate rooms on a plane and then use a star to interconnect these with each other. Seeing my game is cube based I actually do this for multiple levels and then afterwards generate the geometry, collision information and room items from that in memory map. this will only allow you to generate grid aligned paths or rooms but generally works fairly well for a find the exit type of game. I also do not care whether paths cross each other, I do have to mention.
