I guess the novelty has worn off.
That is certainly true to a large extent and perfectly predictable. WWI will always draw a much smaller crowd than WWII.
Unfortunately, after the new wore off, there wasnt enough of an underlying arena to develop its own viable player base. What you have are 4 nicely modeled WWI aircraft hosted in a pretty uninspiring H2H server with no purpose or structure.
I guarantee you, if the WWII arena was reconfigured similarly, the players would find it equally uninspiring. 4 planes. Effectively 2 fields. A single furball. No strat. No goal. No purpose. If none of that is necessary, then take it out of the WWII arena. If it is necessary, why would one expect the WWI to be successful in comparison without it? I truly think it has more to do with that than the genre of aircraft. Given the depth and level of game-play users have come to expect from the WWII MA, the flat, pointless game-play of the WWI arena was destined to fail.
I hope in time we get a WWI arena that is given the same depth of game-play that can be found in the WWII MA. Otherwise, it is just being smothered in the the crib.
