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.
Dying Light: The Beast has this, it’s very refreshing. When all players go into the menu (including the inventory) the game pauses. Should be a standard feature.
