Naughty Dog is working on an upcoming remake of The Last of Us Part 1. Given that this is a complete remake, it was quite expected that the file sizes would be significantly increased.
The Last of Us Part 1 game files have been reported to be at least 79 GB in size. For comparison, the file size of the sequel, The Last of Us Part 2, was 72.95 GB at launch. That is, the remake is slightly larger in size, although it does not have the same scope as the sequel. The remaster, which was released on the PlayStation 4 in July 2014, weighed 40.55 GB on release without any updates. Thus, the upcoming remake weighs almost twice as much as the remaster.
The Last of Us: Part 1 will release on PS5 on September 2nd. It is also in development for PC, but no release date has been confirmed.
