Missing ufo tiles for themes

[Namerutan]

I was reviewing the list of missing ufo tiles:
http://ufoai.org/wiki/TODO/Mapping/Crafts_Tiles

Thinking about the possible landed ufos for each mission type, I think the list of missing tiles could be reduced a lot. Let me know if I am missing something on the following reasoning.

List of ufo types and alien mission types:
Ufos: Scout, Fighter, Harvester, Corrupter, Bomber, Carrier, Supply, Gunboat, Ripper, Mothership
Missions: Base Attack, Build Base, Harvest, Intercept, Recon (air and ground), Rescue, Supply, Terror, Ufo Carrier, XVI propagation

Landed ufos can be found only on a few combos of alien mission type and ufo type:
Scout (Ground Recon)
Fighter (Ground Recon)
Harvester (Harvest, Terror)
Corrupter (Terror, XVI Propagation)
Bomber (Terror)
Gunboat (Terror)
Carrier (---)
Supply (---)
Mothership (---)
Ripper (?)

Excluding Terror missions (always on cities, so highly populated areas: urban or suburban), it is needed only 4 landed ufo types (plus all crashed ufo types) for most mapdefs or themes: Scout, Fighter, Harvester and Corrupter.

As well as for "+ufocrash" there are no landed ufos listed, bunch of ufo types could be removed from several themes, leaving just these 4 types (Scout, Fighter, Harvester and Corrupter):
+beach: nopopulation
+bridge: rural, nopopulation
+desert: rural, nopopulation
+forest: rural, nopopulation
+ice: nopopulation

Landed Supply could be also removed from all map themes, as these only land to build or supply an alien base (there is no mission in geoscape where we can send our dropship, or the mission is alienbase if already discovered).

At least while there are no plans to change (in some future) the mission types available for each ufo type (defined in "aircraftmanagement.ufo").

That is a good point, no use on putting work on UFO tiles that will never appear in game

On the other side we should be careful not to make the missions too repetitive.

[+ufocrash] was actually a workaround when the regular RMA themes missed a lot of crashed UFO tiles. It could be eliminated (its tiles re-used in the right themes) when/if we have enough.)

About which UFOs are currently linked to which mission types: Well, I would say that could change I could even imagine missions with multiple UFOs when/if UFO fleets (escorts) get implemented.

The point is: we are terribly short on mappers, so we should focus on tiles that will actually be used in the game's current state, once that's done we can then evaluate adding new ones for possible future uses, which is not likely to happen any time soon anyway.

Attracting content/art people is not always easy. I think the wesnoth project did a good job here - perhaps some
of this can be translated towards UFO AI, though I think 3D models are harder than 2D paintings.
