Obviously, you're waiting for HW:LG too. Sorry for being a little bit agressive about the games you currently use.
Well, I did not find if you're fighting in « Histwar way » : you choose your Order Of Battle, then you just fight with balanced armies, or if you're moving Army Corps on a map of Europe, and then you solve battles with TW considering the status of the Army Corps and the geographic situation. What did BNL choose ?
According to JMM, there will not be (at first) a server managing battles, the host will have to tell other players his address. If the game meet the success he deserves, he may set one up.
Therefore, your league should be a great way to promote the game by getting new users in contact with the whole community. Moreover, if the NBL organizes campaigns, the success of the game will be undoubtable. Nevertheless, a fragmented community in numerous « leagues » is not desirable. There will be many players from many countries and many languages, but we will want to challenge them, regardless to their own language, so what should we do ?
JMM might decide either to create a single players' community managed by himself (or by the game testers), for all players, or to let people creating groups.
We should keep in mind that many other wargames were flops because players did not get in touch with each others.
Friendly,
Major Pariente.
