I am always curious as to how many folks one person can fight at a time. I was in H2H for some time before I subscribed.
You can have fun in a 8 person H2H arena, no doubt. But that is not a massively-multiplayer-online-game, which what people used to be paying for in Aces High. If number get down to 50 players, you might as well be a IL2 lobby. Numbers decline are recursive. As more people leave, more people leave because more people have left.
I'm not saying that to criticize Aces High or embarrass Hitech. I'm sure Hitech in private would admit a continued numbers decline is an existential threat. The current numbers trend is not sustainable long term. It has to be reversed. Period. Full stop.
I'm not saying it to be a downer. I'm saying it because the people who see no problem are often the most resistant to any significant change because they see no need for change. If everything is peachy-ducky then you just keep doing what you've always been doing, forever. That approach will not end well, and the status quo will not reverse the trend.
I'm not at the level of doom Streakeagle is.

I think the game still has some runway. It better use it.
