I don't think that at all about this Mario/Rabbid crossover. It's not Square Enix making it, it's purely being made by Ubisoft (going by the rumors), it's not going to focus on Mario and the usual main group seemingly of Mario, Peach, Luigi, etc, but Yoshi and some others, so I don't think it's trying to bank on that nostalgia in any way. Now if it includes Mallow and Geno somehow, MAYBE then I would say that, but it's not like Super Mario RPG is the only RPG they've done, there's the entire Paper Mario series and the Mario & Luigi stuff that have come out since then, so this is just another common Mario RPG experience at the moment.
