Got to thinking

[IceFire]

The easy solution is to update Battle of Britain after release with variants used in 1941 or even 1942. That'd mean Spitfire V, Hurricane II, Mustang I, Typhoon, Bf109E-7, Bf109F, FW190A-1 2 or 3, Boston...anything else that you can think of that was used in the channel war. The map would be the same or largely the same and we'd get allot more variation. Of the list only about half I mentioned would be totally new (and most would be useful later in the series anyways). Between a Spit II/V or a Hurricane II and the earlier variations is not very much if you have a dedicated art team working on them.

I'm happy no matter what really...BoB is a wonderful and logical place to start so long as people keep an open mind and don't discount it because they don't have a Mustang to fly right away.
