I don't know if anyone else noticed it, but the signs around the park pointing to different paths and labelling the houses you can find there changed recently and The Last of Us was called something different. I don't have any pictures but am 100% certain of this change.
First weekend, called "Last of Us: Part 1".
Second weekend, called "The Last of Us".
I noticed because of how strange I thought it was to cut "The" from TLOU and also the distinction of "Part 1" which no other piece of info, merch, or marketing throughout the event made. When I went to check it out this weekend, it was changed to the standardized name. Thought that was weird and kinda interesting. "Part 1" could indicate they want to do another TLOU house based on Part 2, but occams razor means it was probably just a graphic design guy not proofreading the sign before it went to print haha!
