Thats most likely true, gone are the days of "total conversions", things are just too complex to redo everything, especially when it comes to the mo-cap animations. But atleast with Rome (if we get tools) the larger scale allows for greater possiblilites. Medieval mods could still be possible with alot of work perhaps, but really the most likely mods would be regionally specific, so perhaps a more detailed map focused on just Greece, or Persia. But all this relies on CA eventually releasing tools for it, which hopefully they will, or else I see them receiving alot of backlash in the future, as Rome seems to be the most popular setting, and mod support will be a very high demand. If they are developing the game with this in mind, tools seem likely. Believe me, I had pretty much given up on modding total war games, before the assembly kit came about, I had only done a few small mods for Shogun. I never expected them to ever release a kit to allow for modding the maps, so I was quite surprised. It renewed alot of my optimism in CA.
