@Green_vs_Red:
Mario,Captain Falcon,Fox McCloud,Princess Peach etc had no fighting abilities prior to the first and second Smash Bros games now they can beat the holy hell out of everyone balance issues notwithstanding.
Every one of those characters have fought in a game before, excluding Captain Falcon. None of them are also just normal people, and live in completely different worlds than one that's like our own.
You do realize that only a couple of COs in the games carry guns much less use them right?
That just makes it worse, because then you're just throwing random humans in the game.
Andy can fight using a big wrench to smack people around with and Max can fight like any of the other nonweapon wielding characters in the game seriously how could that not work in a Smash Bros game?
And they would use a character from the Days of Ruin games if anything, seeing as that's the newest game in the franchise.
Plus Smash Bros likes to add characters from retro games or recent games, outside of Earthbound which is made by the same company. Advance Wars is in the space where it's not old enough to be retro, but not new enough to be relevant.
