Since quite a few people here do not read the mod forum too regularly, yet still play SP games, they might be interested in a mod that eliminates most independent units as recruitables, thus eliminating the massive chaff hordes so beloved by the AI. With the AI forced to rely on its own national units, one should start seeing more powerful armies composed of national units without the need to resort to NI (No Independents) maps and the attendant total lack of independent mages and consequent truncated magical expansion and research options.
