Out of curiosity, what is the map making program? I think the idea of letting the community make maps would be awesome.
I'm using a delicate combination of programs to generate maps exactly how we need them for the game. This, combined with the fact that every map will go through rigorous quality control from Malte (our map designer) and myself (painstaking conversion from 2d to 3d using a series of programs), will make it very complex to train and coordinate multiple people for this job.
That being said, later on if we want to add others to the map development team, we certainly could once we get better at the process of making maps efficiently and are more able to train new team members. For now though, it's just too difficult and too under experimentation to bring others into the process.
As for adding others (apart from Malte) to draw 2d maps, I will need to talk to Malte about that. Malte seemed to be quite confident and comfortable with reproducing the Great Valley as seen in the films, which is our first goal. For simplicity's sake, we may not want to add other 2d map makers until we are completed the Great Valley portion of the game.
