My personal opinion is that it is stupid to buy a console for a single game. In essence you would be paying 600+ bucks for one game.
With that being said, that is something I did when I was younger and deeply regretted it considering that I bought an xbone just for rise of the tomb raider.
I think that if you had an eye on a console and a certain game sold you on it, than I wouldn't think it so dumb.
At the end of the day though, a mans money is their own to do with as they see fit.
If someone decides to buy a console, such a game can help to choose between Xbox or PlayStation. Although that was just a title 😁. A title for praise the game (horizon forbidden west)
