I had this idea for a little while that, whilst complex, I think could be quite interesting. The idea here is that you build a Mass Effect RTS, which personally I'd love to see as a Company of Heroes/Star Wars Empire at War/Total War blend - essentially ground tactical combat is like Company of Heroes, a great RTS with wonderful gameplay mechanics, which I think would suit the Mass Effect series very well. You could then have Star Wars Empire at War style space movement which is very Mass Effect-y, combined with the detailed development options found in the Total War game series. Anyway the important point here is the save game importing. Part of the story mode for this game could involve the Reaper War where the object is not to win, but to deliver essential material to the construction site of the Crucible whilst preventing Reaper or Cerberus forces from attacking it. You can also use space and ground forces to liberate planets, make feint attacks to draw off enemy forces etc - essentially delay them until the project is complete. At some point though Shepards decisions would impact on your forces, the best example of which would be the resolution of the Tuchunka arc. At that point in the game, you gain either Krogan ground forces or Salarian space forces. If Shepard is a paragon (or at least mostly) and kept Kirrahe alive, then if you save the Krogan you also gain STG forces and light Salarian ships, but miss out on stealth dreadnoughts. The same applies to the Geth/Quarian conflict - as the game progresses to that point, you gain access to various forces based on what your Shepard does in ME3. Thoughts?
