First party software. I buy Nintendo consoles for their ip, not their power. My desktop is where I do most of my gaming, but I have an attachment to Zelda games that I don’t think will ever go away. I still have my official prima guide for links awakening dx. I have a map on the wall of twilight princess’s over world.
I don’t even like the switch for portability because it feels bulky and uncomfortable. But connected to the dock, I can forget that it’s supposed to be portable and enjoy my Zelda games. My wife also likes animal crossing, and I got her to play her first Zelda and Pokémon games in the last year, and those were games that shaped my childhood.
So I guess my answer is shared experiences and nostalgia.
When I was younger my parents got a new pc. It had a stupid Game Center trying to sell you games. Being a bored teenager who enjoyed games, I looked through it. I found a game called Dark Orbit. It was the only game I was ever in a clan/guild. I bounced around a few guilds, but I was always friends with the big guilds. I had my own guild for awhile.
One of my friends gave me the top guild because they wanted to start a new one and knew that I really liked their guild tag. Everyone used to hang out on GSC which was a chat client nobody seemed to have heard of. It was like a precursor to discord. I had a lot of really good times hanging out with my guild mates. We sometime just hung out and talked without even playing.
