Tip: Choose the system that your friends have.
It is my "super, duper hack for choosing a gaming system in 2020."
If you are looking to play games with your friends online, then choose the system that they have.
Alternatively, choose the system that you already have and get the games that play on both.
Nintendo Switch, Playstation, Xbox in 2020?
The system itself matters, but if your goal is to play with friends, then you should prioritize that.
