Impressive figures! Looking at the reactions of many fans, I am convinced that the gameplay of Sword and Shield is satisfactory(excluding the animations, that is).
I do have more thoughts about this, though. Not all can be pleased, and I think these sales are the reason Game Freak believes we are happy with what they are doing. What I believe is the truth is that we, as Pokemon fans, cannot avoid buying Pokemon games. No matter how incomplete a game might feel compared to the previous ones, most of us will still buy it as long as the 'Pokemon things' exist.
