I still go back to NW and mess around groupfighting or on 63e siege sometimes. I haven't been in a regiment in at least a year, though. The game is still fun in small doses but its glory days are certainly long past.
I hope BCOF will revive the community but I have my ever present doubts. I personally have very little interest in the game itself - if I were to buy it I would probably just mess around with friends rather than taking it anywhere near as seriously as I did NW.
