I bought so many games on sale after I got my first grown-up job, that just ended up sitting in my library while I played the same 3 games. I bought a Steam Deck 6 months ago and it’s been great for clearing out my backlog. I love being able to play games sitting in the recliner instead of at a desk.
There’s probably a rule or something that says the entire kit has to be different. And if you’re in a scrum with your head down looking at the ball, you’re not looking at the other players jersey colour so different socks is how you tell team mates apart.
