If you count PC, I enjoyed years ago, the retail boxed stuff for Heroes of Might and Magic compendium? I forget, it had HOMM1, HOMM2 + all it's expansion stuff. I played HOMM2 quite a bit, for a while. Also, "ONE UNIT WHOLE BLOOD". It had the Blood game, and all the expansion stuff.
Lately, with PC stuff, I go through GOG, and get their sales of bundles of games. The Bullfrog bundle is nice.
