Nice thread OP
N64 did well in USA (SNES level) but flopped abroad
GC in the other hand flopped everywhere
GBA could have reached 100 million and it was a smash out-of-the-gate, but DS quickly replaced it. Only 3 years in the market before DS release is quite shocking. Still insane it moved freaking 80 million copies with such a short life span
Game Boy sales run was really one of a kind, its sales peak came when it was already 10 years in the market, mind-blowing
