If Universal had won, Nintendo wouldn't exist in the same form they do today.
Assuming they didn't go bankrupt as a company, the NoA arm would have likely been shut down, Miyamoto would have left the company (remember, honor is a big thing with Japanese businessmen), Nintendo probably wouldn't have continued in the video game market, short of, perhaps, handheld LCD type games and either SEGA or one of the American companies (what was left of Atari or Mattel) probably would have eventually restarted the video game market.
