Ya. I used for extra pieces. They may only be the 5 main but id rather buy 2 42 copies than 4 1940 2 pacific 2 europe. Also i wanted the ICs and AA guns mainly. I use 42 to introduce friends.
Old AAP used Union Jack as UK convoys roundel. In AAG40, you could use Union Jack roundel in all UK territories and the roundel used in AAP40 reserved to Indian territories. Just an idea
