Problem is that only vanila system will work, no modding possible to that system... thats not what they told us M2TW will be. (easily modable? dont think so anymore...)
Take M2Tw are compare it to almost every other game that is ou tthere. Most are nowhere near as moddable as M2Tw is. Whilst we cannot mod the source code, we can mod a hell of a lot through text files, and more than with RTW. So yes, M2TW is easily moddable as most of it is done through text files, and most text fiels are not that difficult to understand. We do have limits to what we can do though.
