I am afraid that if Neoqb can't make some money then we will never see them.
Agreed unfortunately.
From hints on the Neoqb boards there seems to be quite a few aircraft on the way none of which are the sort of common hack aircraft that historical campaigns require.
There's the 2 heavy bombers, Gotha and HP that we are aware of plus apparently about 4 more scouts, maybe a 2 seater that I suspect is the Brisfit.
I'd be willing to pay for a pack of say six obsy AI planes, although maybe others wouldn't. I suppose campaign mode could adjust things depending on what we have bought, but MP, more difficult I'd imagine.
