In anglo Canada we have our own version of this that includes at least 1 oversized Canadian flag, at least 1 “FUCK 🍁 TRUDEAU” and 1 “FREEDOM” optionally also on flags or decals, something sloppily painted in white complaining about coronavirus mandates, and getting more common is something insulting Jagmeet Singh.
It would not surprise me if game developers use those screens to gain more time to load assets and initialize things in the background.
I’ll bet they do that with cutscenes and elevators too whenever you’re about to go into a new zone.
