pokemon lets go costs 50% more than sun and moon so the profits are the same roughly and sun and moon came out when there were way more 3Ds sold than switch consoles. this game is a total success
More like 33%, but regardless, Let's Go is likely to make up for it with revenue and profit. Plus you have the Poke Ball Plus to consider. A pretty good amount of preorders for Let's Go are likely with the Poke Ball Plus bundle.
