What are some games that can definitively be said to have invented certain genres?

Off the top of my mind:

Grand Theft Auto III - Open World Sandbox Crime Genre

Super Smash Bros. - Platform Fighters

Demon Souls - Soulsebournes and Soulslikes?

Any others that you can think of?

King's Field came before Demon Souls
