ArmA 3, a great sandbox that I "wasted" a lot time scripting modding or, if you like to call it that: developing for.

A game so great, the Multiplayer-server-browser stores the amount of players on a server in an 8 bit integer.

Someone complaint a few years ago.
Response: " be happy, it were 4 bits not to long ago"

There were Servers who ran into that problem.

To clarify, that only affected the shown number, not the amount of players, at least not directly.
Who likes to be lonely in a multiplayer game.
