In either case, Kingpin is not an important character in the game. The main story is about Mr. Negative and Dr. Octopus. The DLC is about Hammerhead. I don't think it's a prominent appearance at all. Certainly not compared the the Sega game from the 90s mentioned before.
As to where Kingpin fits in Spider-Man's rogues. Consider this, among Spider-Man artists and writers, the gold standard is Ditko. Everyone agrees that there are few characters created Post-Ditko that are as good.
Lee-Ditko -- Chameleon, Vulture, Scorpion, Dr. Octopus, the Lizard, Mysterio, Kraven the Hunter, The Green Goblin, Electro, The Sandman, Molten Man.
(that's 11 rogues by the way)
Lee-Romita - Rhino, The Kingpin, The Shocker
Romita-Andru-Conway - Hammerhead, The Jackal, Mindworm, Tarantula and years later, Tombstone.
Wolfman-Pollard - Black Cat
Stern/JRJR - Hobgoblin
David Michelinie/Macfarlane - Venom
Michelinie/Bagley - Carnage
Among the Lee-Ditko rogues, Kingpin is better, as a Spider-Man villain than Molten Man. So that puts him in 11th Place, and even then the biggest Spider-Man villains Post-Ditko is Venom and Carnage. And I think the Rhino is on the whole a more enduring Spider-Man villain than Fisk. Certainly more popular than Fisk since he showed up in Hulk storylines following that.
