That would be Pokemon Red/Green/Blue, which sold an estimated 10,230,000 copies in Japan according to Nintendo. The best-selling home console game is still Super Mario Bros., which sold an estimated 6,810,000 copies. The best-selling non-Nintendo game ever in Japan is Monster Hunter Portable 3rd, which according to Famitsu sold 4,835,761 copies. For home consoles, the best-selling non-Nintendo game was Final Fantasy VII, which sold 3,937,899 copies.
Blue was a seperate release so it doesn't count. I think Red/Green is around 8 millions. Don't think this is going to be easy but could end up happening. AC is probably close or over 4 millions right now in only 3 weeks and the franchise is known to have incredible legs.
It will probably surpass Super Mario Bros tho.
Why do you say that Blue wasn´t available at retail? Blue is a separate game like Crystal to Gold & Silver. I don´t know why the count them together though :P
Because Blue wasn't available at retail it was only available via special order if you were a Corocoro subscriber you couldn't buy it in shops Blue is more a limited edition in Japan than a separate release which is why Nintendo counts them together and why Blue was sort after in Japan. Yellow is more like Crystal being a third version Blue is not really a third version it's a limited edition of R/G, in the west Blue replaced Green and was a standard edition but then that was 2 years after Japan.
Edit: It seems a retail version came around 99/2000 almost 4 years later.
