Westy,
I agree. I, along with plenty of others around here, played AW DOS.
You are absolutely correct; it never really changed that much.
My point was that this may be the inevitable end of any $9.95 unlimited WW2 ACM game. The players continue to seek more and better "simulation" aspects as well as more and greater "realism" and "immersion" into "combined arms".
It's quite possible that at $10/player/month, a modest sum by any standard in today's world (What does it cost to feed two people at McDonald's, for example.), is insufficient to allow for continuous improvement and new features.
Of course, they may have just ridden what was once a good horse right into the ground.
In sum, maybe $10 doesn't allow enough spare cash to continually "grow" a game.
But it's also possible that they took the money and refused to reinvest in the game.
