EARTHBOUND
Earthbound very much fits the mould of a classic RPG, in fact many modern RPG developers consider it as their greatest influence, from indie darling Undertale to South Park creators Trey Parker and Matt Stone (who now have two RPGs on their resumes).
Earthbound definitely has the most potential of every dormant Nintendo franchise right now, and the calls for a sequel have been coming from fans for years. Since Nintendo seem to be listening to their audience more than ever before (hello Metroid), maybe now is the right time to finally push out a new adventure in this entirely charming series.
There is another possibility, however. Way back when, a sequel was in development for 64DD, the disk expansion to the Nintendo 64. No one knows for sure how far along this potential sequel was before the plug was pulled on both it and the console expansion, but we’re currently living in an age where we’re playing Starfox 2 after 20 years in limbo, so who knows what’s possible if an N64 mini comes to fruition.
