I just meant in the sense that it was in the top 20 games in the US. Of course its the most popular mario kart game at the time, but I had no idea people play it enough to generate a concurrent playerbase that large.
With the general lack of content beyond the initial unlocks/DLC and track packs, I wouldn’t think there was that many people playing essentially becomes a time trial game every day. Then again I play wow now so maybe I do understand.
This is to do with sales, not any concurrent active player metric. Even if it weren’t though, Mario Kart is about playing with friends locally!
