Current Events > Wait, Super Mario 2 (USA) and Super Mario Bros. 3 came out in the same month?

(+) Yeah! (+)

Super Mario Bros. 2 (USA) -- Released October 9, 1988 in the US
Super Mario Bros. 3 -- Released October 23, 1988 in Japan

I'm kinda surprised they didn't just release Super Mario Bros. 3 in the US as "Super Mario Bros. 2."
