  1. The file sizes of the .plr files shown in the video will be a few bytes off, since Terraria encrypts its player files. With a 128-bit (32 byte) block size, all player file sizes are rounded up to the nearest 32 bytes.

    The final file size was 121,792 bytes, but the decrypted player binary was only 121,777 bytes.

  2. I'm curious if Re-Logic will change how save date is stored for researched items specifically because of this video, or if it's such a minor issue that they couldn't be bothered.

  3. interesting, I was expecting map progress (how much of each world a player has explored) to be covered here. Map progress doesn't seem to be stored per world (if you copy a world file directly the copy of the world will have 0 map progress for all characters) so either it is stored per character but doesn't contribute to file size or works differently than I thought.

  4. You should do a video on which theoricaly difficulty / world hardest terraria would be , consider world gen and things such as chest loot and pot generation, on top of overhaul structure
