I took a trip down memory lane and visited the old Smash 4 site. I once again realized that “Damn, that roster was freakin’ amazing!”
Even with (if) Ridley added, I have no idea how it could be topped.
I feel like this when I visit the Brawl site again, it just hit all the right notes for me. You had this very healthy mix of proper allstars (Wario, Dedede, Diddy Kong, Meta Knight), recent characters (Ike, Lucario, Lucas, Olimar) and the unexpected (Pokémon Trainer, ZSS, R.O.B), and there was the initial euphoria of 3rd party additions, one which was the most surprising character we've ever gotten and the other being by far the most anticipated character we've ever had. It also had so much variety on other fronts, you had simple and complex characters, lightweights and heavyweights, cartoony and more realistic characters, humans and creatures, and a wide variety of fighting styles ranging from fists and swords to farts and C-4, there really was something for everyone.
I've long since accepted that Brawl's newcomer roster will never be topped for me, because it gave me everything I wanted, except for my most wanted that is. Because of this I try not to compare things to it too much, the only thing I'll accomplish by doing that is ruin what is otherwise going to be a good experience anyways. I really have no doubts that this game's roster will be great in its own right and will have a similar mass appeal to Smash 4's newcomer roster, because Sakurai is the best at what he's doing.
