It's been more then a week since the release of Hero! Has he impressed to become your new favorite?
I'm still on Inkling right now, but I think Banjo might be an actual challenge when he releases. (Banjo won't be up on the poll until a week after he releases. Though feel free to tentatively say Banjo will be your new favorite)
On a side note, the forum change has kind of helped with polls. You no longer have to entirely restart the polls when adding a new choice. (Though I suppose on the down side you can't make new polls yourself in the same thread. Unless if you're a mod I assume). And if you voted last time you don't have to vote again, but if you had a change you can freely change your vote.
After extensive playing with each newcomer since I got the game, I can honestly say that right now, my favorite is K. Rool. He may not be the "best" of the newcomers but I always have fun goofing around as him.
And with that, I also think Banjo has become my new favorite newcomer of this game. I've never been a longtime fan of the Banjo games, but this inclusion just feels right after so many years and the seeming impossibility of it because of Microsoft's grasps on Rare. The moveset they have is simple and feels right at home among the 64 and/or Melee characters. Fitting of a character that still feels like they are part of that pantheon of Nintendo characters and franchises from the eras that the first two games represented..
I think I've become a Banjo main now. Playing as him feels so good, especially with the down throw and the side special. Sonic was my main before, but I guess he works as my secondary, as I still really enjoy playing as him.
