I used to consider it a Nintendo all star game but now it's just a marketing tool fighter and nothing else. I'm surprised a koopa troopa isn't a character at this point.
Implying it has never been a marketing tool before?
Case in point: Roy in Melee, who was included to advertise a then upcoming Fire Emblem game.
I get that you're disappointed with Wolf being cut. I remember I didn't like Mewtwo being cut in Brawl, but I quickly moved on back then and enjoyed what I had instead of wasting my time lamenting about what I didn't have.
If you really think cut characters are really the bane of this game, I'm afraid I absolutely cannot agree with that.
Glass half empty or half full and all that.
I also believe it's utter nonsense that Sakurai cut characters on purpose, when he's aware every character to be featured in a Smash game has its fans. Some more than others, sure, but all have their fans. However, everyone needs to understand that developing a game is no easy task. If they had time, I'm sure everyone would return and that would be the ideal outcome. And this goes for characters like Mewtwo and Wolf as much as it goes for characters like Pichu and Dr. Mario.
A lot of things people say here are easier said than done. Bringing back all characters would require more time than the amount the development team had. It sucks, but life and reality aren't just pleasantries. Sometimes something must be taken away to make room for something new.
And I'm done arguing about this. This accomplishes nothing. You don't like the game, fine, don't buy it, don't play it. That is none of my business and your own personal choice. I have no choice but to respect that.
