It's eerily quite here... it's been more than 3 hours since the last post :D
So let's change that.
How would you feel if Robin makes it, but you wouldn't particularly like his/her playstyle?
As in, there's nothing wrong with the representation, you just don't like how they played, at least at first?
Would you try getting into it more? I know it's hard to explain if you haven't had that feeling with a character before.
I had this with Nightmare in Soul Calibur 2. I just preferred how Siegfried handled in Soul Blade, but he wasn't in the game and I just couldn't get into his "replacement". I also had something similiar with Link, Snake and Sonic in Brawl, but after playing a while with them, Snake became one of my mains and I really enjoyed playing Sonic. I never really got into Link, but that might have been a balance issue.
I think I would probably try to force myself to get used to Robin's playstyle, like I did with the others. If it just doesn't work out, that'd be a shame, but in Smash I do tend to play even characters I don't really like every now and again just to mix things up.
EDIT: And Hong just mercilessly ninja'd me while I was clicking on post message :D Well, my question still stands.
