Since we have Paul's attention, I may as well pipe up with my own pet WW 1 project idea.
I'm not that engaged with mass infantry warfare. OTOH, the idea of Naval raiding forces of Tars and Marines catches my attention. The largest example of that would be the Zeebrugge Raid, but you could write scenarios for all sorts of other, smaller adventures - destroying a small fuel dump or w/t station, etc.
Commando raids inland with the raiders descending from airships might be another scenario.
Empress already does a nice set of late WW 1 RN raiders.
And they do Reichsmarine counterparts in their Tsuba German Revolution range, but the latter range lacks officer and petty officer figures. If there could be a small 2-figure set to remedy that, that would be amazing!
That would pretty much set up the wargames forces. USN equivalent figures would be the icing on the cake!
