Market Garden needs 'the treatment'. It's one of the most famous battles of World War 2 (it might well, be THE most famous individual battle). I'd like to see someone such as MMP, BF, or perhaps the Italian guys doing something similar (I thought Hazmo originally but I think I was mistaken), give it the 'Close Combat: A Bridge Too Far' treatment.
Individual maps for each of the many bridges small and large, and for the many 'situational battles' such as the river crossing at Nijmegen and so forth, with rules interlinking them all, and all tied into the timeline. Or, if anyone played early Warhammer's 'The Tragedy of MacDeath' (people who have...will know what I mean), something along that line.
I think it could be the best campaign for any wargame ever created if someone threw themselves at it.
One day??
