On that fateful Monday before Thanksgiving, Nintendo and Sega both released products that would have great consequences for their battle. The release dates coincided in the USA, which was also the first territory that both of these products were released.
Nintendo released Donkey Kong Country. This was a game that was quite technologically groundbreaking. It could have passed for a first-generation (2D) PS1 or Saturn game. It sold like mad over the holiday season and spawned two sequels. The DKC games helped keep the SNES relevant during the 1994-1997 phase of the 16-bit wars.
Sega released the 32X, which did a lot of damage to Sega in the long run.
