ARK is the poster child of unoptimized messes, though. It might be a bad example.

Someone hit me with the trivia: How big was Titanfall 1 initially, with its library of totally uncompressed audio for every localization in the base install?

I installed Titanfall last month and it between 50GB and 60GB (I don't remember exactly).

Ark Survival Evolved ? Base game should be around 135GB, and you don't have to install all the different maps at the same time since you won't be switching between them frequently. If you want to run a dedicated server on top of that, those are around 25GB per map, so it is not that crazy I think.

No idea. I am just reporting what I saw when I clicked "install" for her. I'm not into survival games so I don't play it, I just know I was stunned at the requirement and that she had to remove other games to fit it on her PC's SSD.
