What are you talking about? Nobody gives a damn about Donkey Kong? Or Kirby? Or what are you talking about? PSASBR included so well-known IPs like Ape Escape, Starhawk, Sly Cooper or Fat Princess. So fair to the par to games like Earthbound and Ice Climbers.
And Sony had no problem to include Kratos and Nathan Drake in PSASBR, so these aren't cartoony at all, so seemingly that is no problem.
After all Smash Brawl had 39 playable characters and four years later PSASBR only included 24 characters, even including DLC. Two years later Smash 4 included 51 characters and 7 DLC-characters.
So yeah, Sony has much more difficulties to whip up recognizable characters from different IPs than Nintendo.
I'm talking about "there are lots of characters" while you read "all the characters".
A lot is an exaggeration. I named the ones you meant, like Earthbound and Ice Climbers. And I showed that PSASBR has basically an equal amount of such IPs in usage.
