I build Planimeter’s Grid Engine, and we use Tiled for our primary implementation, which also has a terrific generic map abstraction that aligns well to multiple types of level design and game engine architecture. While there is a bit of work one has to do, there isn’t as much as you’d think. If one has enough engine level code implemented already, multiple map formats are feasible.
