Prediction: Kirby Star Allies will flop hard.

[Jumpin]

222,031 copies sold in Japan week 1.
For comparison's sake: it is the second highest selling week 1 Kirby game behind Superstar Deluxe (262K) which went on to sell 1.19 million, Kirby Triple Deluxe sold 218K week 1 and went on to sell 800,000. In both cases, the userbase was significantly higher than Switch's current base, and the software prices significantly lower. So this Kirby game is by far the top for revenue.

For comparison's sake with games in a closer price range: Return to Dreamland did 135K week 1, and sold 790K total; Epic Yarn sold 93K and did 450K total (interesting enough, Epic Yarn was far more popular outside of Japan than Return to Dreamland).

 

While it's fun to see a prediction go WAY wrong, maybe we can change the title of the thread - since the original poster has already surrendered the point and we can actually use it to discuss Kirby's sales success instead of how it DIDN'T flop hard.
