I couldnt agree more with Mako. Surely Orion would have sold many more Boxers if they had also done at least 1 set of opposition. All the SR Crimean sets are great but to cover the basics we still need British grenadiers, French cavalry, artillery for everyone except Russia and, of course, Turks.
I recently decided to buy some sets for a friends children. I then realised how important having a balanced set was, with figures for both sides in it. I opted for an Airfix big box, but if Strelets made a 'Poltava', 'Balaclava' etc they would be a great introduction for newcomers of all ages.
