This has properly been made many times before...
But whats your most Nostalgic game?
A game you used to play as a kid, or young adult, and still brings that feel when you play it again?
Mine game was Roller Coaster Tycoon (PC)
I was totally addicted to this game as a Kid...Always constructing my Rides and achieve the goals to unlock the next park
Very time consuming too, But I always occupied myself by designing my own Roller Coaster Rides, then, as I got better at the game, started Designing underground Rides and forming connections to other Rides.
I still chuck on the Game every so often, just for a quick play for an hour or so
