POKÉMON WHITE 2!
Toss up Between Pokemon Snap and Pokemon Stadium. For handheld games, I personally enjoyed Emerald the most. Started on Red and Blue back in 2000.
I think it depends on who plays the game themselves. If you prefer a mellow game, FireRed is a good start. If you want a more fast-paced game, Sword and Shield. If you want a new style of Pokemon, then Ranger or Gale of Darkness. It varies from generation to generation. Even the spinoffs have different styles and plots that no one is familiar with unless you play it yourself.
Pokémon go because the game makes you play outside and interact with other people
Let’s go pikachu
Pokemon GO. 🤣
