#5 Square and Nintendo
While Nintendo faced considerable competition during the 8 and 16-bit eras, the presence of Square in its corner ensured that the console would be unbeatable in the RPG realm. At the dawn of the 32/64-bit era, Nintendo's insistence to use a cartridge-based format for the N64 was too much for Square to take, and the company began its life as a multi-platform company. The PlayStation took off on the wings of Final Fantasy VII, while the N64 was one of the most RPG-barren consoles of all time.
