TBH, even when correctly balanced like in NASB2, super moves don't really interest me, they can be fun and creative, but I feel they just lack the same punch, as a player; viewer; and opponent, that exists when combos are taking stocks. I'm 100% sure this is different for traditional fighters, and they're a great mechanic casually, but I dunno, I much prefer a more accessible combo system. Ironically, NASB2 makes combos very accessible, perhaps even more so than NASB1 - I barely play that game, but whenever I do, I can always pull off some nasty Donnie combos, so to me, I only really want to use super moves if I especially like them (Rocko's super move for example), and when I do use them, it's just not as statisfying as stringing together Donnie's slime magnet balls into a back air then a light up air.
It was a pretty fun reference in Big's Big World though.
