A reddit user, via Digital Trends, got a copy of Lego City Undercover and found that the game needs a mandatory 13GB installation before you can play it. The game’s box also mentions that it requires an internet connection, though it’s unclear if it’s just for the pre-game install or for other applications.

While retail versions of Xbox One and PlayStation 4 games have long required additional installs, it’s far more of a problem for the Switch, which comes with only 32GB of internal storage. The Switch supports microSDXC cards to add to the console’s storage, but for a lot of Switch owners, having to use nearly half the console’s storage to store installation files for one game is a dealbreaker.

“Forcing physical card buyers to download half of the game is totally unacceptable,” user anh86 said. “Why not just put a plastic game card shell in there and have me download it all?! Totally stupid, won't buy.”

But for developers and publishers, the process behind Switch cartridges is more complicated.

As a result, publishers have to weigh factors like game size and potential sales before choosing a cartridge size.
