How does co-op work in Pokemon Scarlet?

Co-op in Pokemon Scarlet and Violet is pretty cool and works through the Union Circle feature. You just initiate a Union Circle with friends, and they can join your game! You can explore the vast open world of Paldea together, battle wild Pokemon, and even take on Tera Raid Battles as a team. Each player sees their own Pokemon and can catch them independently – no fighting over catches here. Just make sure all players are close enough in the game world to engage in the same activities.

Honestly, the co-op is overrated. It's just running around with friends. Solo play offers a much richer experience IMO.
