I have seen the Western Front arena and it's very good although the old stringbags are not exactly my cup of tea.
No worries. I knew WWI wouldn't appeal to many. Since I wasn't sure it would even work, and it was a pretty large effort, I determined I'd do something I wanted at least(i.e. WWI) because I could always go get a WWII fix in Melee or Scenario.
I have a folder on my desk with a design for a WWII AI-Augmented arena using the same techniques. (WWII: 1940-1943) It would be an Early-Mid war arena. It would be divided into zones with specific plane match-up for AO and era. Early on one half and Mid on the other. Then split into AO. It is not intended to be historical terrain, but evocative of that AO. So you could move around and sample different flavors.
So like zones:
Early
BOB Channel Zone (Huri, Spits vs HE111, 109, Stuka, JU88, 110)
Eastern Front Zone etc
Russian v Finn etc
Flying Tigers in China etc
Pacific Islands etc
Mid
American v German etc
American vs Italian etc
Brit v German etc
German v Russian
Pacific Islands etc
Something like:

Maybe I'll get time and Hitech will let me do that someday. I know it would be more popular than WWI, but I still don't know if it would be popular enough to justify the effort. It's hard to get anyone to do anything other than click on Melee.

Still, it would be a good complement to WW1WF.
It's very kind to offer but not worth expending any energy on. Actually I was just thinking the old furbal lake with AI that would only come one-at-a-time, and / or adhere to the same flight model / flight envelop limitations we had would be worth having even if it was an offline game. Actually especially offline if you get my long-term meaning.
Well, no man can know what the future holds. But for now, there is no reason not to play missions off a Custom Arena. It doesn't require an account.
I can't imagine why HTC configured them with absurd turning ability and energy retention. It's of no use to anyone, new or experienced players alike.
The AI definitely benefits from careful tweaking of the capability variables. Even between aircraft. That's why I feel the Staged Mission path is superior to the random MP spawn mode.
In Staged Missions I can give each flight of aircraft type their own parameters and tell bombers they are not dogfighters!

It's more work, but you have so much more control.
The results are worth it IMHO.
Did you try the mission on the Italy terrain? I'd be interested to know if you felt they were more reasonably balanced.
