What Extinct Game Mechanics Would You Bring Back to Life?

I was flying my drone over some fossil-rich terrain the other day, and it got me thinking what if gaming worlds had their own fossil records? Imagine digging through layers of gaming history and uncovering mechanics or trends that have gone extinct. Personally, I’d love to see the return of split-screen co-op. There was something special about sitting shoulder-to-shoulder with a friend, sharing the same screen and the same experience. It felt more personal than online multiplayer does now. What about you? Are there any old-school mechanics or trends you’d want to revive? Maybe something like cheat codes, unlockable secrets, or even those quirky mini-games that used to pop up unexpectedly? Curious to hear your thoughts!
