I'm probably the only soul here that doesn't really care all that much for story in a fighting (PLATFORMER HYBRID) game. I'm here to kick *** and chew bubblegum, right? That's what it's all about, when you get down to it. I kinda thought Subspace Emissary was kinda half-baked to begin with, especially taking the silent movie route to characterize and to help further the plot. Other fighting games like Blazblue and Guilty Gear at least genuinely attempt to immerse you in their world with storytelling and lore on top of all the fighting (which, of course, isn't a testament to their quality, mind you); Subspace relied on familiar faces and (I guess) their attributed charisma without much depth otherwise. But, I guess I'm just not fond of the kinda medium it strove for to convey its story.
(The mode itself, well, it was kinda...lackluster. A lot of it really, really felt like I was playing through a generic Kirby game with generic enemies, rather than this epic standalone thing that blended many of our beloved franchises together. But I digress.)
That said, I don't really mind modes like that. It's good padding for a game, imo. Same with other single player modes. I would have loved a Smash Run equivalent on the Wii U version, complete with online AND local multiplayer. I spent a considerable amount of time playing that mode on the 3DS version. It was a lot of fun.
