In terms of a campaign for MAW, I have a working campaign starting in Sicily in august 1943. However, I have made so many tweaks to MAW to get it running smoothly that it is not worth releasing the campaign file on its own. What I have been toying with is a slimmed down, stand-alone version of MAW to enable combat in late 1943. Releasing something like that is problematic, as it probably contravenes the original terms of use for MAW 1.31, not too sure if I can ever release it.
There are some nice models for the later stages of the MAW theatre (think latest Spit VII - VIII package, Early Typhoons package, Beaufort package, Fulmar package, Kittyhawks, etc etc) that are crying out for use in the toolbox, but MAW in it's current form with African skins for vehicles and aircraft, is only set up for around 1940-41 - especially the spawn sets.
Once I have it working reliably, I will put the question out as there are a few of the original MAW team around, to see if they'd mind a small stand-alone release for 1943 Sicily-Italy campaign.
