I dont know if this has been suggested.. but I suggest 'grabpacks'
A lot of the OLDER games requested by people seem almost TOO cheap, or TOO old, to pay $6 for. What if there was 'grabpack' games, smaller ex-DOS games that you grabbed in make it yourself packs,
Like, I dont know, someone chooses some smaller games, say things like diggers, elite, REALLY old DOS games, and they get like 5 for $6. It may not work out, but it is true that it seems a bit odd to pay a full $6 for cannon fodder whle paying the same for something big like Knights and Merchants... just an idea, because I can picture more people would buy the really old games if that happened
