Before I get started let me say that I am running this with the currently newest Proton and DXVK. Aside from a few crashes (which might have happened on Windows as well, I remember this game being buggy) there were no issues whatsoever - no compatibility modes or tweaking required, it even runs in 4K. I thought the main quest line was longer, I finished it in basically one go together with the main quest extension Broken Steel in about 10 hours. Quality is ok, not overwhelming though. Definitely liked the quests more than in Fallout 4. Mothership Zeta has a cool setting, but gets super repetitive quick. I haven't yet played the other extensions. All in all, I think this game might be a little steep for full price at 20$; at a reduced price you should definitely give it a try.
