Well...
I have a submarine hunter game where one side are destroyers and the other are the submarines.
Then my dad has a World War Two North Africa Campaign game. It is massive and missing a LOT of pieces. Tried playing it once but many things were and are missing.
There is also a World War One game set on the Western Front that me and my dad attempted until he said that when he played with his dad, they didn't get no farther than one or two hexes here and there.
