After 50 hours, I completed the main story and got basically every upgrade along the way, so I feel like I 100%ed it even though I didn't. This is an immaculate game to really thoroughly play once, and that's enough. The story becomes incredibly engaging in the last 10 hours, so obviously it's hard to recommend if you don't have 50 hours to give but if you do, I think it well deserved the hype.
