Gamers may have begun to shy away from the now more expensive PS5. U.S. April data highlights a 30% decline in PlayStation console sales compared to the previous year. Before the impending Switch 2 price increase, Nintendo’s handheld extended its lead over the competition.
It was Nintendo’s fastest selling console of all time. So, yes.
The SEGA Dreamcast had the Guinness World Record for Highest Revenue Generated by an Entertainment Product in a Single Day.
For this record, set in 1999, it sold >225,100 units to generate $98.4 million USD in revenue. Since then, it has only been replaced by video game software and not consoles (from my research, the Dreamcast was replaced by GTA IV in 2008, and held the record for ~9 years though I dont have any books or historical site references prior to 2008 too verify).
Of course, everyone remembers the Dreamcast for how highly successful it was, and its massive sales numbers.
“Fastest selling console” is a meaningless title when more people buy video games every year compared to the previous year, so “fastest selling console” is always going to be next years console until the market crashes.
