Strange thing happened at a party my wife and I hosted this past Sunday.
The group of people we were with would look at you funny if you mentioned "Final Fanstasy", we all played Wii Sports and Wii Play and had a lot of fun. But even that wound down around 1am and people were kinda getting ready to leave. For a lark, I started up Super Mario Bros. 3 on the Wii - amazingly, everyone surrounded the TV and we all took turns playing through the game. Everyone stayed up playing until 4am, and had a blast.
I just found it astonishing that SMB3 still has that much appeal.
