Ok Comrade Alexeo, just to point out a few things -
A. You can no longer make provincial campaigns with the currents version of M2TW, so you can only have one large map - or creat a program to start before game to switch which campaign to play.

B. The models are completely different and your current models will not be of much use due to a change in the format and way the models in M2TW work, and no modelling appears to be possible at the moment.

Now on to what I can do - I can script, make the campaign map, I can edit the .txt files and as soon as the .texture format is understood I can skin them. Also I have epxerience with websites and could probably get us hosting at medievaltw.com
