TL;DR
The name "startup setting" and the message "cannot be changed while a game is running" imply that you cannot change them in existing games, when in fact you can, you just need to exit to the main menu first.What ?
Change the name "Startup settings" to something clearer.My suggestion: "Game settings". Because they apply to the entire game, not just the current map.
Also change the message "X settings cannot be changed while a game is running" to "X settings must be changed in the main menu".
(Out-of-topic Bonus: When changing map and player settings from the main menu, show a message "This will only affect new games. To change settings of an existing game, load it first.")
Why ?
Pretty much every week, I see this exchange:- Hi can I do this?
- Yes it's a mod setting.
- I saw that, but it's a startup setting and I already started my game.
- You can still change startup settings for an existing game, you just need to quit to the main menu to change them.
- Oh thanks!
