I've decided to add a list of things I either missed or got wrong. I've tried to credit all the people who brought them up in the comments, but I apologize if I missed anyone.

Kino Der Toten

The projection room is shown on the screen in the original version, but was harder to see on consoles (gavcobob, Group-935, danny2896, Superball01, daemonvanmeir9697)
