I remember someone online saying that Super Mario 64 is the video game equivalent of Citizen Kane, and like I've never seen the movie, but I know how much it impacted movies going forward so I think that implies to Mario as well
this game was released in 1982

The game has an innovative text-based physics system, developed by Veronika Megler. Objects, including the characters in the game, have a calculated size, weight, and solidity. Objects can be placed inside other objects, attached together with rope and damaged or broken. If the main character is sitting in a barrel and this barrel is then picked up and thrown through a trapdoor, the player would go through.
Unlike other works of interactive fiction, the game is also in real time, insofar as a period of idleness causes the "WAIT" command to be automatically invoked and the possibility of events occurring as a result. This can be suppressed by entering the "PAUSE" command, which stops all events until a key is pressed.
The game has a cast of non-player characters (NPCs) entirely independent of the player and bound to precisely the same game rules. They have loyalties, strengths, and personalities that affect their behaviour and cannot always be predicted. The character of Gandalf, for example, would roam freely around the game world (some fifty locations), picking up objects, getting into fights and being captured.
The volatility of the characters, coupled with the rich physics and impossible-to-predict fighting system, enabled the game to be played in many different ways, though this would also lead to problems (such as an important character being killed early on). There are numerous possible solutions and with hindsight, the game might be regarded as one of the first examples of emergent gameplay.
