It says 36 people are playing the mercenaries mod. But the last post on the taleworlds forum was from like 15 or 16 months ago (May, 2011). c-rpg has 36 people playing in NA or EU even during off hours, and during peak Crpg has 300-400 people playing, and is updated regularly by a decently large mod team.
I think I'll be sticking with c-rpg. But thanks for the shameless promotion.
