I didn't check the minimum requirements, but if I had I would have been even more annoyed when 20GB wasn't enough to complete updates.
Yes! I have two machines I use for VR stuff, and I face this every time I come back to VR! I even have the full hard drive allocated, not just a 20GB partition.
Ouch! Watch out for the coming Win10 fall update (October). It might brick your setup, as it needs (supposedly) minimum 20 GB free space.
Note/disclaimer: Not sure how true this is, couldn't validate it personally. That said, I'll definitely ensure all of my Win10 system boot partitions have at least 30 GB free space.
If you used a gaming console the same way you are using your main computer (booting it into a separate OS for most the time, until you all of a sudden wanted to play a game) you might also find that there's updates waiting to apply, and some games require the OS update before they'll play, etc.
Plus, there's a bug in the installer that requires a full re-download.
That was just for the OS. He obviously has a separate data partition to install games on (unless he only likes retro 8bit type games).
Personally I think they've really nailed this.

This has been exacerbated for me because initially I only allocated ~20GB for the Windows boot partition, which is plenty for Ubuntu but apparently nowhere near enough for Windows. Even at ~30GB, I have to do things to reduce the amount of space Windows uses (like disable hibernation, manually compact WinSxS, etc) so that those big named updates can complete.
In short: Windows is too high maintenance for infrequent use.
