You should play NW more often. Right now I can see 120 players on Minisiege, of which less than 20 have a regimental tag. That's less than 1/6 of the server. Not all players play with regiments or even enjoy doing that. I can't check for the 15th since I'm banned, but I have no reason to believe that they have more regimented players. While I can see why people would prefer Bannerlord over Warband Native, I don't see any good reason to prefer Bannerlord over Napoleonic Wars. The 2 games will be completely different. Most players play many other games without abandoning the old Napoleonic Wars, so why would they abandon Napoleonic Wars for Bannerlord? Actually, it's even possible that Bannerlord would bring back some old players in their old NW regiments, because most NW regiments will also play on Bannerlord.
