Just picked up the BattleDock for Switch 2! This thing is so cool, it adds a piece to the dock that replicates the look of a GameCube and actually has functioning controller ports! It has swappable faceplates and comes with all the retail colors :) Super sick. It's only $40 and you can use the code "GCG" at checkout for 10% off!
