I agree that Donkey Kong content is a lacking, but as @

stated, it's the first-impression the series gives that hurts it. The Mario spin-offs are quite guilty of this as well, when DK courses in Mario Kart are mostly jungles and having more characters besides DK and Diddy is rare.
Though a lot of series in Smash have this problem with Pokémon having mostly stadiums, Fire Emblem having arenas or castles, Metroid having mostly lava stages, Star Fox getting space levels with Arwings and the Great Fox and so on. Hell, even Kid Icarus mostly gets Skyworld levels. The stage selection for KI on the Wii U version is essentially Skyworld and "Skyworld meets Temple".
Though a lot of those series do get stages that stand out more: Pokémon with Spear Pillar and Unova League, Kid Icarus with Reset Bomb Forest, Donkey Kong with 75 m, Metroid with Frigate Orpheon and such.
The only series that get more variety in stages are Mario and Zelda, but even so, Mario always gets the obligatory Mushroom Kingdom stage set in green plains with ? blocks and whatnot. The 3DS selection for the Mario series is rather poor given the similarities between 3D Land, Golden Plains, Mushroomy Kingdom and even the first part of the Paper Mario stage. Throughout the Smash series, the franchise to get the most variety in stages is, without a doubt, The Legend of Zelda when every stage comes from a different game and features a different scenario. I mean, take a look:
- Hyrule Castle (recurring location of the series)
- Temple (based in dungeons overall, particularly those from Zelda II)
- Great Bay (Majora's Mask)
- Bridge of Eldin (Twilight Princess)
- Pirate Ship (Wind Waker)
- Skyloft (Skyward Sword)
- Gerudo Valley (Ocarina of Time)
- Spirit Train (Spirit Tracks)
Though I'd say this is helped by how the Zelda series features many different locations right from the beginning of the games. Hyrule itself changes a lot in each iteration of the series and several games feature different worlds altogether.
No, I'd rather not have
any bias in Smash, personally. If anyone was to take over the helm of Smash development, I would think it'd be either Miyamoto or one of the other big names.
Though a Reggie-made Smash game would probably fly off the shelves due to fan reaction alone.
Reggie doesn't and wouldn't make games. He's not a game designer.
Anyway, there will always be some sort of series bias when it comes to Smash as long as the developer in charge has worked in one or more of the series featured in. Hell, even Bandai Namco gets a lot of love in this game with it being the only third-party company to have more than one IP in Smash (it has a crapload of them, in fact), items and more than one Smash Run enemy.
If Miyamoto were in charge, the Mario content would likely be through the roof. If Retro was in charge, Metroid Prime and DKCR+DKCTF would likely have a lot more content. If Intelligent Systems were in charge, there would be more love for the Fire Emblem series. With Sakurai, it's Kirby and Kid Icarus. This is due to two factors:
- Creators always work better with their own creations than those of other people (in the latter case, it's often necessary approval by the IP owners and directors).
- Developers have easier access to assets from their own games than those from other studios. This point is especially valid for the abundance of KIU enemies in Smash Run and KIU trophies in the 3DS version, as Sakurai himself admitted that the team had a whole load of assets from KIU that could be easily ported over, thus enabling them to add a lot of content without spending too much time and budget. I don't think Sakurai wanted to promote his own game, but just found a practical way to add more content to the game without spending resources. It's no coincidence that the 3DS version is the one to have such overabundance of KIU content, which was a 3DS game. The Wii U version hasn't got nearly as much Kid Icarus content in comparison, having the same number of stages as most series, having around the same number of trophies as small series like EarthBound and Fire Emblem, with the only thing standing out most being Smash Taunt conversations, something the Star Fox series also has.
