The latter was a nominee two years ago but failed to make the cut that time around. Along with Half-Life, the other games that just missed out this year were Asteroids, Call of Duty, Dance Dance Revolution, King's Quest, Metroid, Minecraft and Ms. Pac-Man -- all of which were finalists in 2018 as well.

The museum said all four inductees "significantly affected the video game industry, popular culture, and society in general." The Mortal Kombat and Super Mario Kart series are still going strong, with Mortal Kombat 11 dropping just last week, while Mario Kart 8 Deluxe continues to thrive in sales charts and there's a Mario Kart mobile game set to arrive this summer. Solitaire helped countless office workers and students while away the time when they got bored with life (or Minesweeper), but you might be less familiar with Colossal Cave Adventure.

Despite its lack of polygons, the 1976 text-based adventure "still offered a fully-realized realm to explore, with treasures to find and puzzles to solve," according to the museum. That paved the way for "an entire genre of fantasy and adventure games, and it directly inspired other pioneering titles, such as Adventureland and Zork."

It's absolutely a worthy quartet of inductees. They join the likes of John Madden Football, Tomb Raider, Final Fantasy VII, Sonic the Hedgehog, Grand Theft Auto III, The Legend of Zelda, The Oregon Trail, The Sims, Space Invaders, Doom, Pac-Man, Pong, Super Mario Bros., Tetris and World of Warcraft.
