I think a debugging console should be added to the game. I’m thinking of the one that any game made with Valve Source has. This would be useful for server administration as well as (possibly) performance improvement.
How this would work is that the player can toggle what is shown on the screen, ranging from connection status to client-based problems. They would also be able to input commands. In addition, this would also keep your chat clean, only leaving it for player messages.
Here’s an example of me giving myself an imaginary item.
/health Codian 50 (gives 50 health to Codian)
/thirst Codian 50 (gives 50 less thirst to Codian)
/hunger Codian 50 (gives 50 less hunger to Codian)
/rad Codian 50 (same as health but with radiation)
/Health off (player gets infinite life, only for singleplayer and needs to be turned on in the menu)
/thirst off
/hunger off
/rad off
/oxygen off
/energy off
and more
