NES for the win. This is because some things are hard to measure. Retailers were actively hostile to console gaming when the NES released in the US. A few years later people are more enthusiastic for console gaming than they'd ever been before. So many great IP were started on the NES too: Mario, Zelda, Metroid, Final Fantasy, Dragon Quest, Castlevania, Metal Gear, etc.... The NES created the foundation for all console gaming going forward.
