I would absolutely love to see some WA versions of more Boxer Rebellion troops.
First, there are many more options for Chinese - mounted boxers, imperial troops, mongols? Some of those could double duty for a Back of Beyond type use, and some, depending on weaponry, could be used as far back as say Opium Wars, Taiping Rebellion, etc.
Second, there are the European troops. There are a lot of interesting troops that took part in (for instance, and always popular with wargamers) the Peking Legation campaign. You could do Sailors (which would work for Italians, Austrians, etc. - all wore a common late 19th century Sailor outfit, just different headgear), French Marines, US Marines, German Marines, Russian Infantry (which also double for Russo-Japanese War), Japanese Infantry (also for Russo-Japanese War), Russian Cavalry, Japanese Cavalry, British infantry, British Royal Marine Light Infantry. A lot here to get all to, but something that WA could do, is a few sets, each covering troops for several of these options. I'm imagining something like a 30-40 figure box, split half and half between several different types of troops. Maybe 10 each of US, French, and German Marines. The players of small skirmish games, get one box and done. The "Sword and the Flame" players, could buy two boxes, and have 1 unit of each type. The serious gamers would get a half dozen boxes HAHAHAHA - sorry, got carried away with dreaming.
Of course, doing the nationalities separate is probably better for head, weapon, and pose options. Russians and Japanese would be perfect in 28mm, I know I'd go nuts, and you could do a box of infantry, a box of cavalry, and a box of command/MGs/Artillery for each of them. That would cover several good campaigns of the Boxer Rebellion, but would also open up the Russo Japanese War.
I don't need to tell you guys how to organize or schedule sets, all I'm saying is that I think more Boxer Rebellion is a great idea.
