Looking at
this page (which, btw, needs Panzer Lehr and KSF added), here's what I don't own (since its shorter than what I do own!)
Airborne (original)
Airborne Remastered
Edelweiss (original)
Go For Broke
Grossdeutschland 1946 (little interest)
Heros of the Soviet Union
Indian Unity
Lions of Finland
March on Leningrad
Nihon Silk
Power of the East
Siege of Leningrad
Waltzing Matilda
Its not like I'm ever going to play all of the scenarios/games I have now, and I can see me purchasing a bunch of the ones I don't have that aren't out of print at some time in the future.
