I am not bothered as long as they are imaginative and well sculpted and give me joy.
Some -"Heart of Darkness" type Africans from up the Congo
Some - French or other 18th cent citizens revolting and not so revolting.
Some - more Mongols
Some - more Indians from India (not in uniform) of the 18th/19th c.
Everything sounds good to me. But I think you often refer to periods still manufactured by several companies. Because I'm posting here at the strelets forum I think it's the right place to name some periods which fit perfectly to the multifigure (more than 40 different figures)range of strelets. They would be fantastic for skirmish games:
1) French and Indian War (all parties)
2) Mogadischu 1993 (a complete Black Hawk Down range)
3) Legends of the old west (different cowboy, desperado, mexican, lawmen etc. posses)
