I think one thing people underestimate when discussing NASB's future is the actual prime Nickelodeon audience - kids - and I don't mean this in the sense of "they're gonna add Parker the Cloud or another Loud Sister!" but rather in the sense that, because of Steam's hardcore-oriented image and requirements, nobody really knows how successful the game is with Nickelodeon's target audience who would prefer to play on the sofa through a console with their friends and family. From what I've seen the game is pretty consistently high on the Switch's fighting game sales charts, though I admittedly don't know if they're recent or all time. I've been recommended a few NASB videos on YouTube that seem to be by kids (Kinemaster watermarks, "X Lover 201Y" usernames, "My reaction when..." titles on clips of characters cheering, so on) and they've very rarely if at all been negative so I doubt the lack of a items at launch and super moves is much more of a deal breaker for them than a lack of 8 player mode or stage morph.
