As I matured as a gamer, I've seen a lot of changes in the last three decades of video games. But one of the most profound experience is still manifested in kids from the 90s - the local multiplayer or as we call it today: Couch-Coop.
Without a doubt, the biggest impact of the coop experience was made by Nintendo with their 4-player game Mario Kart. To this day, people have their N64 ready to go when friends come over and want to do something together. Albeit video games are still a stigma for many people, who would prefer the outside world.
