Native gameplay, within the Calradia setting, with a strong emphasis for improving convenience, gameplay and adding new options (such as quests) to the overall M&B: Warband experience. Any version of M&B warband from 1.153 to 1.158 will work, but the mod requires the use of the Warband Script Enhancer v3.1.5 which is included in the download.
Simply the ideas involved here compared to most other Warband mods are revolutioanry - clearly lots of work had gone into this.
With economic micro-managing and the introduction of unique stats and units (NOT minor factions!), this game really outdoes most other mods.
