I am a Brit who loves flying off carriers (even though I suck at 'landing on' carriers
) but we have to bear in mind that it was mostly a USA v Japan thing.
Britain did have carriers in the Far East but few people, outside of Brit enthusiasts like me, know much about what they did there and the rest of Europe had no active carriers at all. While the US may be a big market it does not make up for lack of interest from the whole of Europe & Russia. Such a shame the Graf Zeppelin was never completed; maybe someone could just 'pretend' like they did with IL2 1946
