For anyone curious about Frontiers' debut performance compared to NPD performances of previous Sonic games: The last Sonic game to enter the Top 5 of a specific platform (or in Frontiers' case, a platform ecosystem) was Sonic and the Secret Rings, back in March 2007. The last Sonic game to enter the Top 10 of a General Top 10/20 NPD chart was the NDS version of the original Mario & Sonic at the Olympic Games, back in February 2008. No previous Sonic game to date has ever debuted in, let alone entered, the Top 5 of a General Top 10/20 NPD chart. (At least, not based on the information available.) It must be noted though that unlike past NPD reports for Sonic games; which gave chart rankings for specific platforms. Frontiers here is listed for general platforms released by a publisher. Not an issue with 'Nintendo platforms', which may as well be a Nintendo Switch chart in all but name; but 'PlayStation platforms' (which includes PS4 and PS5 SKUs/releases) and 'Xbox platforms' (which includes Xbox One and Xbox Series [X\S] SKUs/releases) do fudge the performances a bit. I will also drop a warm take in that I think Frontiers' performance here owes much of the credit, if not most of it, to the live-action movies. At least in the sense of the films being widely promoted in mainstream circles by Paramount, and the films themselves being box-office hits. Without them, I imagine Frontiers' performance would be closer towards the norm of past Sonic games.
