Thanks, second post updated! Where did you get the lists from?

Only March and April are missing~

How is Odyssey not #1? That doesn't make any sense to me.

The power of Stardew Valley.

...In fact, I'm glad Stardew Valley is #1. Let Mario win in physical sales.

It seems that Stardew Valley is doing great! Would you recommend the game to a person who dislike Harvest Moon/Animal Crossing games? I'm not saying it's a bad game, but I think it doesn't fit my tastes.
