You could argue that 200GB isn’t a lot, and that’s true in a way since some AAA titles — specifically, Call of Duty: Black Ops Cold War — are pushing over 300GB of installed size..
That just makes 200GB sound even bigger to me. The loss of 200GB isn’t as important when you go from being able to install 25 games down to 20. You really don’t need that many installed so you can cope. But when your available space drops from 5 games to 4? That’s a much bigger deal.
