From VG Chartz roughly this is the total of hardware numbers by generation. I'm starting at gen 4 because it gets iffy before that with accurate numbers, its less then 100 million anyway so who cares.
Gen 4: (SNES) 100 million
Gen 5: (PS1) 285 million
Gen 6: (PS2) 385 million
Gen 7: (what the fuck knows) should end around 535 million
Gen 8: What do you think? I'm guessing around 775 million, video games just keep getting bigger and bigger every year, it only makes sense to go up.
