I bought CMSF with the Marine expansion, but I found them not that impressive for me. So I just stopped buying the British and NATO expansions. The report after a battle in CMSF is a little bit simple, because it just shows you how many guys wounded, killed or missing but nothing else. In POC, of course, the demo, after a battle I can check what happened to my single unit, and when I found one of my Jagdpanther destroyed 5 T-34s, I really felt great.
However, I will buy CMBN just because this time it focuses on WWII...
