I've heard lots of people over the years say they are too mature to think about the console wars. What does it matter to them that Nintendo's Wii U was a sales failure? That doesn't impact one's personal enjoyment of it!
I would ignore network effects at your own peril, people. Hitching a ride on a successful console car (as long as it's not a train) has a lot of benefits. I'll outline three of them in this article. The last one is the real reason this article was written. The first two are just for narrative build-up. ...Building away!

This is the most obvious application of network effects. In a world where most multiplayer games are locked to the console they are on (no cross-play), getting all your friends to be on the same console as you is pretty important. If they don't have that console, you don't get to play with them. Then you'll have to make another group of friends. For a lot of gamers, doing that is tough stuff. And you'll get estranged from your first group of friends.
Console popularity and consolidation saves relationships.
I mean, why do you think Wendy doesn't do anything on the site? She hasn't had a Nintendo console in, like, decades.
But what if you don't play games with friends? What if you play games by yourself?
