For fun, SNES games as I recall, hard to get numbers this far back:
Street Fighter II: The World Warrior: 6.3 million ww
Street Fighter II: Turbo: 4.10 million ww
Final Fantasy III (VI Japan): 3.42 million ww
Killer Instinct: 3.2 million ww
Chrono Trigger: 2.9 million ww
Super Metroid: 1.42 million ww
Super Star Wars, Super Empire, Super ROTJ, Super Castlevania (phew), Contra III would probably have to be considered, I can't find numbers for those though.
