Pretty much title. It is annoying when you are playing some online co-op game (where time matters) and you cannot pause it. Server pause option would amazing in case you have to deal something in real life. I found this issue annoying in Peak and most farming games.
Stardew Valley has this to pause game in online and I hope more games would add this option.
I grew up playing NES, where it was super common for either player to be able to pause the game. Pausing and unpausing right as someone is making a jump will never get old.
