Ok, So I can find no evidence that there was EVER a Super Mario Land Bundle.
There was Re-release, but a re-release just meant they kept publishing the title as there is still demand for it on GameBoy.
With this info, I think Super Mario Land is the official Non-Bundled king of singular sales.
When I was originally asking the question, I had not figured on didgital downloads, and re-releases on newer systems. I really didn't want to include them for this debate.
Just one game - on one system. Who's the all-time best?
Its a very intriguing yet confusing topic when you think about it
