Eh, not exactly. The Zelda series has tons of trophies(and now Spirits), music, stages, a decent amount of items, and had tons of Stickers too. Plus lots of NPC enemies in Adventure Mode in Melee. More than some series too. It's pretty well represented in terms of having lots of content.
It's not varied for the playable characters, but to be honest, the only major one missing is Ganon right now for the trio. Then you have lots of viable choices, though I doubt he'll throw in more than 1 at this point(which completely kills the Champions as is for options, but still at least helps ones like Tingle, Ganon, and Impa. And maybe Vaati too?).
