### Instruction: I'm writing a blog post on the history of video  games in the 80's, 90's and 00's. I plan to include these games in the analysis: Mortal Kombat, Doom, Final Fantasy VII and Myst, World of Warcraft, Grand Theft Auto, Populous, SimCity, Final Fantasy X and Guitar Hero. Please group these games based on the decade they were first released.
