Sometimes I wonder why people are more aware of the breadth of SEGA's IPs compared to Nintendo's IPs, even though the latter lasted longer. What I mean is, yes, SEGA is best known for Sonic and to a lesser extent Puyo Puyo and Yakuza, but people are also aware of their other IPs like NiGHTs, Jet Set Radio, Virtua Fighter and Panzer Dragoon. In fact, there is a Wikipedia page that chronicles all of SEGA's IPs.
Nintendo on the other hand, had at one time got a complaint that they never made new IPs since Pikmin before Splatoon surprised people with its success that even convinced its naysayers. That is a misnomer given how many types of IPs they got out even between 2001 and 2015. Rhythm Heaven and Brain Age are among a few IPs that Nintendo had during those times, not to mention how overlooked the success of the Wii IP was. Of course there's also including famous ones like Mario, Legend of Zelda and Pokemon. In fact, this page chronicled a list of over 200 items in the list so it's not as if they are having a shortage of them, despite not every one of them reaching the heights of their best ones.
I suppose this is one thing that Smash does very well: it puts a lot of Nintendo's history into the spotlight, and while not every IP is represented by a playable character, they are still there to educate us on the amount of IPs that Nintendo do have.
