Marvel's Spider-Man topped the US September charts, according to NPD. The game set a new record for a PlayStation exclusive with the highest launch when it comes to revenue.

"Spider-Man, the best-selling game of September, achieved the highest launch month dollar sales for any PlayStation exclusive in history, and is the seventh largest launch ever achieved by any game on any PlayStation platform, said NPD Group’s Mat Piscatella.

"Marvel’s Spider-Man generated higher dollars sales in its launch than any other game this year and currently ranks as the third best-selling game of 2018, and the No. 8 best-selling game over the last 12 months." Thats very impressive. The high development costs that Sony and the developers invested for the game and the players are rewarded.

I don't know. I think the marketing of "Everyone's Here" and "the biggest crossover in gaming history" can potentially attract casual buyers. Unless you don't think there's any interest in seeing Mario, Link, Cloud, Mega Man, Ryu, Pac-Man, Sonic, and Simon all in one game. Sure, it kinda worked for Smash 4, but the Wii U was an unattractive system (as much as I liked the Wii U). With the Switch, you got a popular console that's selling well and with more potential to grow instead of a console that had very little momentum.

it was also on 3ds and the system was pretty popular. 

But thats a point, Zelda BotW is curently at 9.3m only on Switch that has 20m install base, and it keep selling great how install base is growing, each quarter Zelda sold at least 1m on Switch, at end this year it will probably be somewhere around 12m and LT will easily pass 15m. Zelda TP on sold around 7.3m. So we talking about huge difference in sales already.

SSBU is much more than just ultimate version of Wii U game, also has much bigger hype, its type of game that will sell hole Switch life span and it coming to platform where strong Nintendo games generaly sell much better than on previous Nintendo platforms. IMO 15m is bare minumum Ultimate will do.

I wasnt on 3DS, Ultimate is not WiiU/3DS port, it took previous game like foundation for game and build much more on a top of previous game, that why you have changed some core mechanics, new moves, new mods, much more new fighters, much more new stages, new music...much bigger hype.

Also, games on Switch generally selling much more than they do on 3DS, espacily when we talk about big Nintendo games, Mario 3D Land sold 12m LT on 3DS, Odyssey will most likely pass that number on Switch at end of this year.

Can we stop talking about Smash and other things irrelevant to Sept NPD?

this is like comparing cod WII vs infinity warfare its not all about different systems like some people make it out to be, its just Nintendo changed the formula and elevated to a new level imo. of course i do know switch is selling better software wise, just saying its not the main reason mario and zelda sales are mindblowing, they both scored 97 which is mind blowing, and had huge hype because of how Nintendo changed the formula, and fans as well as gamers loved what they were seeing. single player games are starting to become big again.

Well, seems like the claims that Spidey wouldn't give a bump were wrong. Congrats PS4 and Spider for the expressive month lead and YOY up.

People are still laughing, it ain't happening. 

But its not point only about 3D Mario and Zelda, MK8D and Splatoon2 are also selling great and those games are not 97 games, and intresting enough those are all biggest games that Nintendo released until now, pattern is clear, next are Pokemon Let Go (even its not core Pokemon game) and Smash Bros. For instance even Xenoblade Chronicles 2 very fast become best selling Xenoblade game. Smash Bros Ultimate will easily become also best selling Smash game, same we can expect from Animal Crossing, to become best selling Animal Crossing game.
