The Legend of Zelda: Breath of the Wild (NS) is the most successful stand alone Zelda title (not counting remasters/other versions)

Not bad, but when counting sales inflation of games compared to the 90's its really closer to being 5 million to OOT's 7.6. Take the best selling game of this gen and compare it to the best selling game of the ps/n64 gen to find the difference then divide BOTW numbers with that difference to get pre inflation sales numbers. Decent but not ground breaking

Notice that it's barely been a year - both the franchise, and that it's a launch title would lead us to believe that the game should easily sell another 50% over what it's currently at.
