Basically yes.
This really shouldn’t be a problem for most games. I don’t believe Roblox is wrong in their estimate. I just believe that Roblox has no reason to have this limit if only 30 experiences reach that limit currently. It basically kills or severally harms any future projects that would go above those limits.
If your data is over 1 MB, you should probably look into optimizing your data storage. This limit is really only a limit for games on the scale of Minecraft or similar, where a full chunk of completely unique non-storage blocks (65,536 blocks) may take up 327.68 KB.
