They're just cutting costs as you get thing like Puyo Puyo Tetris which is £35 on Switch because of the cartridge price where it is £25 on PS4, now with this 8GB cart WB can sell LEGO cheaper then the other versions.
They have put out a statement saying you don't need to do the download and can play without it but 13GB is a huge amount to be missing, that I'm hoping someone like DF does a video with and without the 13GB patch to show what is actually on the cart as their will be people who won't have a internet connection, won't have 13gb free and will have to go buy a SD card and in the future when the Switch online is cut off, what will we have left.
