Here are 3 of my suggestions for command line arguments, they would be amazingly helpful for my program!
1: -nosplash: hides the splash screen that pops up when you're opening the game
2: -background: starts the game in the state of being in the tray and so it doesn't show the game window (until you interact with the tray icon)
3: -noexec: doesn't run scripts BUT logs errors still
