This may sound crazy, but i think the game is capable of having new sides added to it... i don't see any need to add new file types (the thing that stumps me from adding a new theater) and I have examples of it being done between ra2 and yr.
Given a corresponding collection of files with the correct prefixes (eva, load, etc...) addition of a new support category unit... and a whole bunch of other things, is it possible?
Olaf, you better tell me what I'm missing now so I don't get my hopes up... I have yet to see a mod add a side (so I'm assuming there's some reason it can't be done) , is this actually possible?!
(please note that I am not going to acknowledge Fallen Angels as adding a side - that isn't the same as what I'm speaking of)
