Medieval Mod

[ruff_hi]

I'm thinking of running a medieval SG but I would need a mod. I'm looking at these units (catapult, crossbow, explorer, knight, longbow, pikeman and maceman) and limiting science research. Not sure about religion - might remove it. Will definitly limit the civs to those around during medieval times (monachy, slavery, vassel, etc).

Does anyone know of such a mod? If not, I am happy to put one together but I would value suggestions.
