If the Mario series never existed, the modern day video game industry would be much different, the primary competitors would be Sega with the Sega Tor, Atari with the Atari X, and to a lesser extent, Nintendo with the Nintendo VGC (Video Game Console). We might just be in 16-bit SNES graphics (which wouldn't be bad). Nintendo's mascot would be Donkey Kong, Mario would be Jump-Man and be the antagonist and be pure evil and torture DK. No online games.
