Honestly all of that would stress me out.
The few times my partner and son leave me alone, I tidy the entire house and get every chore done with the goal of being able to do nothing (except walk the dog).
Being able to shower, dress and chill out to my own schedule is heaven. I would probably put star trek, Stellaris or Minecraft on. Maybe.. make a coffee and eat chocolate all day with a book
Just to add.
Look at any hobby in your life and break out the money spent vs the enjoyment you got out of it.
For example the Cinema costs me £10 and a film is 2 hours long, meaning my fun time costs £5 per hour.
A £100 console would have to provide me 20 hours entertainment for it to be comparable to going to the cinema.
These days any PS4 game will have 10-40 hours content, but buying them costs money. Popping on CEX website the most expensive PS4 games are £12. Assuning you only get 10 hours of fun from a game...
The question you should ask yourself is are there 3 games on the PS4 you are interested in playing?
