Thinking about it, the only place where there's really Sakurai bias on Kid Icarus is Smash Run.
[collapse="Breakdown"]Characters - Around 3 characters is what I believe to be perfect representation from series with lots of characters. You have the two most important characters and one less important but still noteworthy and relevant character. This is one of the reasons I'm upset with Lucas and Wolf being cut since they brought something from their respective series that cannot be replaced. Lucas was the protagonist of his game and Wolf was a recurring foe from his series, after all.
Stages - 1 stage per version. Nothing really wrong here.
Assist Trophies - 2 like many other series. It's an okay number when major series like Mario, Zelda and Metroid get more and EarthBound has 2 as well.
Items - 6 items isn't bad. Mario, Zelda and other series also have a lot of items. Plus, KIU's items work really well in Smash, which can't be said about some other series' items.
Smash Run enemies - This is where Sakurai went overboard by having a bigger number of enemies than even Mario.[/collapse]
And I have been happily drinking all the tears of people who wanted Bowser Jr with his paintbrush.
Clown Car Bowser Jr. in Smash is one of the best things ever.
(He still uses the paintbrush for the Final Smash.
)
By the way, speaking of Mario Kart 8's DLC, how does it work for online play? I mean, not everyone will have DLC content, after all...
