damien: But maybe you can elaborate on what "V tylu vraga series" is?
"V tylu vraga" was the original title for Soldiers: Heroes of World War II and as you can see [url=http://en.wikipedia.org/wiki/Men_of_War:_Assault_Squad]here[/url] it's still officially being used for the newest Men of War games. That Western publishers did not keep a consistent name for the first half of the series doesn't change the fact that it is in fact one series.
The only game from the series that did not have "V tylu vraga" in the title was Men of War: Red Tide, ironically the first game from the series that introduced the Men of War name in the West which has been used consistently ever since.
