Assuming AGEOD gets the kinks out of it, it seems to me that the WON engine, with all its diplomatic and economic features and flexibility, is a potentially great fit for a remake of TYW. It would also allow for an expanded map (although it would be a cut-down version of just the main central europe and surrounding areas).
I am wondering what the thinking is? This seems like a good route eventually, even though patching the original TYW may be OK in the short run.
