The Fortress 2 could be named "The Fortress: Lords of the Land". Idea is to marry Castles with Lords of the Realms II. Arguably combat was the weakest part of both LOTR games (not counting LOTR3 as a valid sequel since it was some silly mistake accidentally named after the famous game). Castles + LOTR would be a perfect match -- player would get a thrilling strategy game with additional bonus of fantastic castle building! It would be great to go from one territory to the next waging a campaign of war whilst creating fortifications to protect a realm. Then player could introduce seiges and all sorts making them meaningful as well as multiplayer aspects. It would be ideal to see such mix done as The Fortress 1 but that would make it much bigger game which may not be a good idea for the first game in this series.
