Not really.
People said they didn't like the idea of Shovel Knight had reasons that weren't inflammatory and were polite when expressing them.
Treating a franchise like its dirt and stating that it's an RPG for five year olds, saying Isaac is literally the worst written character ever and taunting the fans of said series by saying its entire existence is why Camelot can't make them anymore is just laughably spiteful.
Dude, I could care less if you like the game or not. It's when you go out of your way to **** on it where I have a problem.
I'll weigh in on this because I have nothing better to do.
I'll say it outright, I don't like Golden Sun. After playing the first hour or so and going through the first two dungeons, I did not like it. The story is pretty generic and the game seems dated overall.
HOWEVER
I think Isaac would be a great character for Smash, and out of all the Ballot front-runners, he's one of the characters I support the most. He'd be completely unique, and just because I didn't like the game doesn't mean I can't like the character. I will say the music was great, and the game was okay, I just didn't like it personally.
This, seriously. And where the flying **** is Wolf?
Can we not make characters out as shoe-ins? We've seen it happen with K. Rool, Ridley, and a plethora of other characters. What happened when they didn't get in? Mass anger and disappointment. (Pre-ESRB, another Wolf fan expected him in the base-game, and when he didn't get in...it wasn't pretty.)
Segway-ing into another point, I don't see why some people are so against Shovel Knight. Literally all I'm seeing is the same reason people got mad at the clones, or WFT, being either, "It's not [insert character here], so it must be a waste of space and I must be angry," or the fact that he was in one game. Has that stopped any other character? And while Shovel Knight is an indie character, I imagine this more as a Banjo-Kazooie case. Nintendo sees talent in Yacht Games, and they're going to lock them down. However, instead of a hostile takeover by buying shares, they'll ease into it. Get some exclusivity by putting Shovel Knight in Smash, then BAM! Hit em' with the takeover and make them second party. Nintendo already let Rare go, and this is their second chance at something good, they're not going to let it go.
And I'm sure that if he gets in, the moment he's shown everyone will flip because he's a new and original character and he'll be hyped.
