I'm sure I've told you this before, but there's more to a character than what they fight with. The key thing is HOW they fight. Steve is noticeably different yes, but disregarding the fact that he has no kicks (save for I think one attack), he's as different as all the other characters are from each other. I can't play Steve like Eddie like Heihachi like Jin like Xiaoyu like Julia like King like Yoshimitsu, etc.
Yeah I agree with this. And my main beef with Lil Mac is a weak one, I admit that. Its just like... in Tekken, despite the fact that everyone plays very differently (not arguing this at all, I love Tekken and I appreciate the varied character design), if you boil it down to aesthetic basics, its mostly just punches and kicks. Characters like Steve, Christie/Eddie, Devil Jin, Yoshimitsu, etc. that have a very apparent difference in their fighting styles hugely stand out because of their focus on punches/ducks, dancing shenanigans, lasers pew pew, and swordplay, respectively.
Mac would fit in just fine in a game like Tekken for the same reason the above characters do. He'd focus solely on punches, which is unlike nearly every other character. In Smash, sure, his focus on punches would be unlike nearly every other character, but in a less exciting way. From a purely aesthetic view, I don't think its as fun to see a character with a host of different punches vs a character like G&W who has a wide array of different methods of attack. @Shinhed, this applies to Marth as well. I don't really like him aesthetically because every attack (barring like 3 of them) can be adequately described as a sword slash. That isn't much variety.
From a gameplay standpoint, Marth is awesome. From the spacing/tipper game, to his wavedash length (in Melee at least), he's a lot of fun to play as and against. I have no doubt that Little Mac would be the same. Quite frankly, you could take the dullest character in existence and give him the most amazingly deep, complex, and fun moveset imaginable. It doesn't take much. MYM has roughly ten thousand examples of this.
I guess what I'm trying to say is that I'm dumb for not liking Little Mac for the reasons that I have, but at the same time I don't really think I can be swayed. Gameplay-wise, I'm sure he'll be just as fun as any other character. But, similar to characters like Marth, there is very little variety he can have in the aesthetic of his gameplay. Captain Falcon at least has his manly persona to help him out to be a
badass normal. Mac would potentially be a badass normal... but without the badass.
