This edition certainly packs a lot of Mustangs related goodies!
Gamers of a certain vintage will no doubt be familiar with the house magazine of the Avalon Hill Game Company - the General. Over the course of some thirty plus volumes the General covered all things Avalon Hill related - optional and additional rules, scenarios, analysis and turn by turn refights.
When I acquired my copy of Mustangs initially I had not thought about the General but thanks to the Aerial Wargames and the Avalon Hill groups on Facebook I was introduced to the following website:
Although designed for gamers of Advanced Squad Leader it also has the complete back catalogue of the General in PDF format.
David Manley messaged me and very kindly emailed two key editions of the General that have really expanded the base game beyond recognition. There are scenarios and a whole raft of additional aircraft types which are really going to give me plenty of variety. Needless to say my reading list has increased significantly but that is not a problem as I am still waiting for my additional aircraft to arrive from Heroics and Ros.
I would certainly recommend the above website whatever Avalon Hill games you play - I am sure that there is something for everybody!
