I have heard that 10 to 20 million copies of Super Mario Bros came bundled with the Nintendo Entertainment System. The same goes to Tetris for the Game Boy.
If you deduct these copies from the 40 million copies of Super Mario Bros
and from the 30 million copies of Tetris, the former actually sold under 30 million and the latter sold under 20 million.
As standalone games, they didn't hit the 30 million mark.
Are there any unbundled games that actually broke the 30 million mark in home-gaming history?
