What this guy ^ said . Years ago, when the Wii was hot and Marvel Ultimate Alliance 2 was announced, I was on an IGN board. The idea came up that the Wii version should have Nintendo characters like Link and Samus as hidden unlockables to help give the Wii version tons more value in the vein of Link being in Soul Calibur 2. Most people in the forum shitted all over the idea, talking about how Nintendo characters had no place in a Marvel game because they aren't comic book characters and aren't canon to the game. I'm like, "What the hell about this game strikes you as canon? What, is Marvel vs. Capcom canon to the comics and nobody told me?!"
Seriously, what is this sacred cow of gaming that makes people think certain characters can't cross over? Where is this hidden rulebook of gaming, or if these are unwritten rules, can we please start writing them down?
Because the idea of Marvel games is that they involve Marvel characters, duh, as well as the idea of Smash is that it involves videogame characters. Once you start allowing other stuff in, the game's core identity changes.
The idea of Mario Kart games is that they involve Mario characters, duh. Did Link and the Inklings change that? It's still called MARIO Kart, right? You still see MARIO characters front and center on the cover. The "core identity" didn't change a bit.
DId Link, Heihachi, Spawn, the female Spartan, Yoda, Darth Vader, Starkiller, Lloyd Irving, Ezio, or Devil Jin change the identity of Soul Calibur? Three of those characters are from comics and film.
Did the xenomorph, the predator, Jason Vorhees, Freddy Kruger, Leatherface or Kratos change the identity of Mortal Kombat? Not a single one of those guest characters are from fighting games... and outside of Kratos, games in general.
Lol at you guys really thinking one character on a roster of 70+ is going to suddenly make the game go from "Super Smash Brothers" to "Goku and the Pips."
