I think it will be a bit harder to do a campaign like a couple of years ago, 2.12 SPC seems to have a lot more variation in how squadrons are moved around so there would soon be a lot of contradictions between players.
That said if players Kept Mum about bases and other squadrons this could be reduced.
For a 1 person Battle of Britain AAR, I think 2.12 will be fantastic and I would mention that the BDG team is small and everyone is busy trying to polish off things for the release so some new people to just give it some playing time would be of great assistance.
