The NPD Group have released their full North American sales data for October, and, like every month so far in 2018, sales were up year-on-year. Consumers spent $1.5 billion on games and hardware, up a hearty 73 percent from $894 million last year. That’s not a huge shock, as the month saw the release of both Call of Duty: Black Ops 4 and the long-awaited Red Dead Redemption 2, although where those two games fall on NPD’s monthly software chart is somewhat surprising. Despite all the hype, and tripling the launch sales of its predecessor, RDR2 came in second place, with Black Ops 4 nabbing the top spot. Of course, RDR2 was only on sale for six days in October, so it wasn’t entirely a fair fight.

On the hardware front, the PS4 chalked up another win, achieving an all-time October sales record. NPD didn’t reveal where the Xbox One and Switch ranked in comparison to the PS4, but, overall, it was a good month for everybody, with hardware sales up 19 percent to $2.7 billion.
