With a VR headset: with Alyx, it's one of the best game I enjoyed playing :)
You ARE in space. That feeling when you hop in your spaceship, take off, point to the sky and come up in space...
Sure, after a hundred hours of playing, I came to the conclusion I had enough, I had seen everything that was to see in the game - even without completing it, never reached the center of the galaxy - but it sure was worth its price.
Adapt your working days ? I work a 9 to 5, but only 4 days a week - I'm off on wednesdays. I managed to live with my 80% pay. The benefit is I work 2 days, then I'm off, then 2 days of work again, then off again, and loop this... The weeks are never "too long", it's only a "2 days week": monday then immediately it's friday, twice a week ^^. It gave me a nice feeling of balance between work and private life (of course, working 3 days a week would feel even better, but I don't want to live with a 60% pay, it is a choice I had to make: I like my house, I like my car, my motorcycle, going on vacation, upgrading my gaming rig when needed, and so on).
