I get that people don't think it's worth the full price tag, but how many times can you make the same point? Because they are "bad" Konami is selling Super Bomberman R for more than people think it is worth. Deeming an objective worth on a game is a slippery slope, but either way, just don't buy it. It's hard to argue that Konami, a business, did something wrong when this game is the best-selling entry in the franchise in the past 20 years.
This game selling well proves 2 things, I think. First, it proves to other third parties that their games could sell on Switch, which is a good thing. Second, it shows a potential demand for Bomberman games, so the chances you get another, BETTER, Bomberman game are higher because this one sold well.
