Small question about mods to RO.

[Pripyat]

Are there any worthwhile ones aside from the couple that are on Steam, that is Mare Nostrum and Darkest Hour?

Carpathian Crosses (http://www.moddb.com/mods/carpathian-crosses), but I guess there are less players than in those mods you have mentioned. Yet RO community from Poland do CC night once a week.
