Final Fantasy 15's 170 GB PC Requirement "A Mistake," Director Says
It's actually not a "mistake". It's just not the bare minimum. It's what is required to run the game at maximum graphical settings & textures:
The PS4 version comes in at ~57GB and the XB1 version comes in at ~51GB.
This is getting a bit out of hand. The average download speed in the USA in 2017:

The issue here is that this is just the mean, and while the median looks good too, neither of these figures conveys the more enlightening truth that roughly 1/3 of American customers (mostly in more rural areas) are still running on connections that operate effectively between 2Mbps-10Mbps.
Split that difference: 6Mbps. That's 750 KB/s (or 0.75 MB/s).
To download a 170GB file at that speed would require 226,667 seconds: about 63hrs-- nearly three days. Don't plan to use your internet while that is downloading because you won't have enough reserve bandwidth to smoothly stream a 240p YouTube video. No competitive gaming online. Your internet becomes unusable.
