Even at the end of development it’s a sensible choice. It’s the default strategy for catering to machines with slow disk access. The risk of some players experiencing slow load times is catastrophic at launch. In absence of solid user data, it’s a fine assumption to make.

The first impression matters is the thing. This was John Carmacks idea on how to sell interlacing to smartphone display makers for VR: the upsell he had was that there's one very important moment when a consumer sees a new phone: they pick it up, open something and flick it and that scroll effect better be a silky smooth 60 FPS or more or there's trouble. (His argument was making that better would be a side effect of what he really wanted).

Call me a dinosaur, but I don't consider a 154Gb download before I can start playing a good first impression.

In fact, I would seriously consider even buying a game that big if I knew beforehand. When a 500Gb SSD is $120 Aussie bucks, that's $37 of storage.
