In general, the Switch is just incredible. For those unfamiliar, the system can be used on a television as with typical consoles, but it can also be taken out of the house (or into a room of the house without a TV) as a portable gaming system with its own battery. Because of this, Pokémon Let's Go can be played on plane rides, road trips, on line at the grocery store, and more.
Additionally, the Switch's controllers have more than just buttons to help them function. In Pokémon Let's Go, whenever a player is trying to catch a wild creature, the remote is motion-sensitive, so players can actually "throw" the Pokéball themselves, rather than hit a button that says, "Throw Pokéball." It might give your kids a sore arm at first (this might be something I speak on from experience), but it's one of the coolest parts of the game.
