^the NES was a smashing success from the get-go, and it got the titles. For a system that lasted over 8 years (if taking Japan in 83 as starting point), it got plenty of support from its 2nd year from third parties. Yeah the big hitters were mostly japanese, but japanese games prevailed for like 3 generations, and even when there were notable exceptions (like Mortal Kombat) the majority of big games were mostly from japan.
