In the future, each of our RMA themes should be able to support all types of UFOs. Also, one time the rescue missions should also take place within our RMA.

Including the dropships (3), crashed Phalanx aircraft (8), UFOs (7) and crashed UFOs (7) this makes 25 required tile definitions. As, from my experience, the max amount of tiles the parser can read is limited at 65 (?), this leaves 40 definitions for the map tiles.

+forest and +country already exceed this number, other themes will do quickly once somebody finds time to build them up. So I request to support parsing a much higher number of tile definitions as a long term goal.

There is also some special case to think of. We have a pool of shared tiles to make it easier to maintain the frequently used dropship and UFO tiles. This requires having one template for each of the required tiles in this pool. Now, it might be possible for a map to use the dropship tiles from this pool, but still have its own tiles for UFOs and downed Phalanx craft. This essentially results in a lot of tiles are counted twice. In this case the parser reads all definitions of the shared tiles (25) and the definitions for UFOs and downed Phalanx craft (23) from the map.
In addition, it might even be possible to not only have the described tiles shared, but many more.
