My god, I love the ROTK series. I've been playing them for about five years now, I wanna say. Granted, I'm not a big fan of the older ones. They're more difficult to me than say ROTK X and ROTK XI. XI put way more thought into it all, though and made it that much more difficult to conquer the map [which I have only managed once].
I'm excited to see new portraits and the like from this game, though I'm doubting they'll change every single one as they didn't from X to XI. However, they did add a wider selection of created officer portraits from X to XI so, XII gives me hope that they'll continue to add new ones and keep the old ones at the same time.
