I volunteered long ago that if AI was brought to the AvA, I would take care of the AI "programming" work, giving the AvA staff scores of "missions" to choose from. It would just require an AvA staff member to choose and launch such missions at the time & place of their choosing. I'm sure there's much more involved than just building offline missions, but the basics would still be the same & I'm still willing to do my part if the AvA staff is ever given this tool. I think it would breathe a huge breath of life into the arena if players could fight large historical battles any day of the week, instead of waiting for FSO, etc.

I can only imagine how awesome your efforts would be.
It's definitely right that Hi-Tech needs to put most of the development into his bread and butter, but this is something HTC could do for the history/immersion fans out there.
As Combat Tour is shelved, the AvA is the perfect place for Combat Tour "lite".
I understand, the biggest attendance will always be in the MA, and there is still the feeling that forced AvA set ups led to the demise of other sims.
There is however, a smaller community of historical/immersive play fans, that deserve some development time as well.
I can rarely attend special events and since I just don't care for the "every plane, from every country, at any time" concept, it's nice to have the AvA option, and I'd like to see some development there.
In fact, you might say that it is only the AvA that kept HTC from losing me as a customer.
I believe that enabling an AI mission generator for AvA could lead to some great things for the "historical immersive" player community.
