15gb is good. Overwatch is like 10gb after updates.
I'm pretty sure if game developers compressed the sound files of game just a little instead of having them pretty much as raw data, I'd have more than 50gb left on my hard drive with like only 5 games installed from discs.
Seriously, Diablo had like 15gb of other languages I'll never use but had to install it. 
...yes this was a slightly out of context rant.
Hmm, pie.
