[2019] Game Size

So, I'm not sure what you are basing these wild claims on, but they're not accurate. If we, for instance as you claimed, stored the zbrush files for all the characters in the game files the game would likely be in terabytes, not gigabytes.

We actually have a mod pack with the real source assets planned (as has been mentioned at previous modding dev streams) so modders actually can get a hold of the uncompiled files to be able to make changes to them, but there is no announced release date yet.

Originally posted by Vacca: I still fail to understand how games like The Witcher 3 with all its DLCs or Warhammer Total War with mortal campaign and all its current DLCs are smaller than this game, but ok.

The multitude of tradeoffs between disk size, loading times and patch sizes as well as how steam's update system works would likely be an entire dev blog just on it's own. The short version is that we most of the time have prioritized patch download size and loading time when given a choice so that levels load fast even if you don't have an SSD.
