The Master
Midfield
Would Metroid not be the first female? I guess that was more a thing at the end rather than straight away.Charlie Brooker did a 2 hour doc years ago on this subject. Obviously alot more detailed being 2 hours long but he's absolutely right. Each of the games he discussed brought something entirely new to the gaming world
Games featured were; Pong, Space Invaders, Pac Man, Tetris, Super Mario Bros, Parappa the Rapper, Mortal Kombat, Starcraft, Tomb Raider, The Sims, GTA (any of them) World of Warcraft, Call of Duty 4, Wii Sports and erm... Papers, Please (as said before there's a reason it was listed)
It's not about what your favourite game in the past was, Tomb Raider is iconic because it featured the first ever front cover female superhero type character.
Tetris is owned by Vladimir Putin, or whoever becomes President after him.
That's the definition of a "game changing" game.
If I had to narrow it down to just 3 out of that list it'd probably be Pong, the first ever game to be featured on TV during 1 of Bruce Forsyth's shows, Space Invaders for the big arcade gaming boom and Starcraft, nowadays we live in a society where we watch others play games on YouTube or Twitch, people in Korea been doing that since the 90's and it'd feature on National TV over there.
