Some further thoughts on this topic and other data over the next few weeks.

Some pretty obvious data – Lots of WWII. A significant proportion of modern titles, fueled in part by LNLP series games plus non Korea/Vietnam era titles, series titles from the old GDW – Third World War and Assault series plus a swag of SPI titles.

Lots of ancients, quiet a decent amount of Napoleonic titles also.

The big weakness! American Revolution and to some extent ACW (which consists of tactical monsters).
