I was just wanna come out here and say something. I have just finished writing an epic chapter of my multichapter Super Smash Brothers fanfic, and I have greatly calmed down from earlier. I would like to speak my personal opinions on the differences I can see and prove between 3DS and Wii U.
First off, looks. Looks aren't everything. People love the old Smash Brothers, for N64 despite being one of the graphically worst games on the console. In Super Smash Brothers for Wii U, Sakurai is aiming to make the game brighter than it was in brawl, but still keep some details since that's possible on the HD console. He even has realisticaly blowing grass in the background of Battlefield, which is a pretty great detail. The 3DS version looks similar, but also more cartoony, which I love. I hate the idea of one of Nintendo's best franchise being T-Rated. That means the responsable parent/guardian would likely not buy the game for their kid, which would make them miss out on the greatness of Smash. The way Smash 3DS looks gives me the feeling it will be E10+ rated, which I further love. Let me just point out here, that most of these characters aren't meant for realistic settings. Mario, Kirby, Pokemon, and Sonic the Hedgehog are all lighthearted video game franchises that focus mainly on bright themes and just the fun of doing impossible things. The cute characters, Yoshi, Kirby, and Pikachu gradually become less cute the more realistically you depict them. I prefer the bright and colorful cartoony style because to me, it fits the characters far better. Plus, for all I like Brawl, the graphics are just far too dark and gritty. It's depressing. 3DS is superior in visual style for me, because I prefer artistically over technically.
Controls. I don't really care about the controls, honestly. I can customize them, obviously, so I'll set Grab to X and Shield to both L and R. if that doesn't work, I'll try a more natural setup to make it feel more like the GameCube controller. Let me just mention I'm also a casual player, so I'm not exactly super picky about things. I might get into competitive play someday, but that's the future and I'm focusing on the here and now.
Roster size; Quite honestly, we have 33 characters confirmed right now, with three months left until Smash 3DS releases. I honestly don't feel we have any need for doubts. I personally, am not worried about further delays/time constraints. As far as I know, And PLEASE DO correct me if I'm wrong, DLC can help an unfinished game become finished. Say that Sakurai decides at the last second to add in, say, Mii Mages. He only gets the character halfway finished before the game's release. Because it's the optimal time for release, Sakurai will release the game even with the unfinished character. What will happen? He will take the unfinished character off of the data of the cartridge, take some time to finish the character, make it DLC, sell it in the E-Shop. Players will spend a dollar or two, and get a full, new character. And you didn't even have to wait extra time to get the rest of the the awesome game! (Seriously, correct if I'm mistaken, because I don't wanna come off as an idiot for a simple mistake)
How something sounds depends on the person, so I'm not gonna say anything on that.
Thank you, goodnight. (it's 3:00AM where I am and I just finished a more thna 5,000 word chapter of a fanfic as a newbie writer)
