So, are you saying that 1c are being lazy introducing Storm of War with a relatively easy to create campaign?
I think it makes sense, it was one of the first major air battles/campaigns in the war and to me beginning SoW early in the war is great.
Hopefully they will continue with expansions based on a certain battles or campaigns and introduce them in approximately the order they occurred.
The first expansion might for instance be called Storm of War: East Africa.
The other way to do it would be to go by order of popularity, and surely that has its merits, for one it would probably generate profit faster as the big campaigns and theatres are better known and has more famous aircraft in them.
Personally though I think that the best way would be to do it in a chronological order and to keep expansions centered around a specific battle or campaign, with the expansion supplying maps and aircraft as needed. Where applicable these maps could then be reused for later expansions with newer aircraft and a new campaign.
This way 1c could possibly generate more profit and a larger customer base in the long run as also smaller and less known battles and campaigns would have their place and would get the attention they deserve instead of being lost as small insignificant add-ons after all the big guns already been introduced.
Well, that's what I think.
