I mean honestly, none of my friends have the same gaming interests as me either.
We all have Switches but I'm the only one who is into the Xeno series, I'm the only one who digs deep into indies and retro-style games, I'm the only one chasing JRPG (and JRPG-style) games.. We do all line up on Zelda and a small few of my friends play Kirby and Yoshi, but most of what they play is the sort of stuff I
don't: Pokemon, Animal Crossing, Mario Kart, Smash...
But the fact that there's such a huge span of tastes being served on Switch I think is part of why it's been so successful.
