Together with the rest of the recent moves SEGA has been doing (I suppose it'd be SOA's doing, but I wouldn't know) with putting ROM Hacks on Steam Workshop, Sonic Mania and so on.. They must know generally what people think about Sonic 4. Obviously, there are so many weird facets of Sonic fans so I don't disbelieve in the idea that some people really like Sonic 4.. but generally, the opinion that Sonic 4 (both episodes) are middling to bad is pretty canon in the grander scheme of things. I don't think rebranding Sonic 4 is a bad idea.. I'd show that SEGA understand what Sonic 4 sits in the canon of Sonic games, which is, not really the sequal to Sonic 3 & Knuckles most people wanted. I'd liken what I'd like happening to Star Wars Extended Universe books getting rebranded as Legends something or other. Still stories with some worth, but not officially part of anything. Sonic Mania might be the closest thing to Sonic 4 we get, but it's also "not Sonic 4" in some areas. I'd wish for the 'Sonic 4' name to not be used, with what that implies. A name can imply a lot. I wouldn't disregard the value in that.
