What does a First Grade Teacher do? You always remember the name of your First Grade Teacher. It's not just because they taught you your ABC's, how to read your first sentence, or how to sit at a desk for more than five minutes at a time. First Grade Teachers usher new students into the rest of their academic careers.
While Nintendo of America seems quite happy to give Super Mario Bros. a publication date of October 18, 1985 (as seen on the Virtual Console service, its NES game listing, and in other places), not all gaming historians seem comfortable with that date.
As explained in great detail by writer Frank Cifaldi on Gamasutra, Nintendo's official release date of 18th October 1985 is contradicted by other evidence, mainly related to what games were available for the 'trial' launch of the NES in New York and the subsequent national release in 1986.
