Why is a group of four players the standard for the majority of games?

Question

Be it TTRPGs, board games or video games, a group of four players is the standard size.

DnD and adjacent systems balance their challenges around a party of four. Most boardgames come with four colours for players to choose from. Most video game consoles only can connect four controllers and most video games like Smash Bros and Mario Kart only have four slots? Why is that?

Answer 1

Imagine you have a game in which you need 10 players to play it. What an absolute nightmare having to not only have 9 friends, but 9 friends who wants to play that specific game. Then set a date/dates to actually play it with all 10 of you able to show up. It’s just very inconvenient the more players you need to have.
