Is the mod intended to be played on 'standard' BtS maps, or will it be played on a Middle Earth map as the intended design? If on a middle earth map, what period is used? Will it include Aman (Vanyar) and Numenor?
The reason I bring this up here is play balance. I'm not sure if the intention is to make all of the Civ's balanced from a play standpoint, but in stadard BtS type games, many of the naval advantages could be a little weaker. Therefore, the Teleri and the Numenorians may be a little shortchanged.
If we use a Second age map, for instance, presumably Numenor would be on an island to the West. (If they sail farther west out of sight of the island ....) Anyway, on an island these characteristics could be good. Being on an island in Civ gives both advantages and disadvantages
Good - can build up without worrying about outside attack, plenty of ability to expand
Bad - Without contact can fall behind, hard to stop a monster Civ from forming onthe mainland.
Anyway, depending on how these factors line -up, we can decide if we should boost them. The Lanun in FfH are very powerful becasue of their Pirates Coves, we could make a weaker version for sea-borne trade. This could be useful if the game is played on standard BtS maps. Obviously, the opposite is true with archipelago, where the sea traits become very powerful.
Best wishes,
