i feel that WWIIonline is not the same as WB or AH. it is more of a combat feel then a flight game.
WWIIonline has better tanks, trucks, inf, AT guns and towns with what feels much more real...and needs much more thinking.
AH what i have seen so far is a much better flying game for me as it is not full real... we only have black outs.
we really can not put WWIIonline in the same pot as the flight sims.
as for numbers.... 1800 to 2100 on line in WWIIonline
