'bout time I updated the journal.
Through a combination of noticing it on my own and being on the Bumbleking forum (several members of which seem to have a dim view of adaptations that do their own thing), I wondered: Why do I have a problem with character designs in the Sonic series that stray too far from the "standard", but alt-continuity characters from Megaman are perfectly fine?
Short answer is that in Megaman, the main cast is (for the most part) always redesigned to fit the aesthetic of whatever alternate continuity they're in, whereas in Sonic, it's usually just a few stylistic tweaks (with the exception of Robotnik/Eggman). Therefore the blatant disconnect between the game and non-game characters that tends to crop up in Sonic stuff, doesn't in MM.
People often cite Archie-Sonic as a good example of disharmonious character designs (though in recent years they've put a lot of effort into reducing that); I see your Archie-Sonic and raise you a Fleetway-Sonic--which oddly, I hear almost no complaints about (though that may just be that the fandom for it is smaller/quieter). Does anyone know what the hell kind of lizard Grimer is supposed to be?
Heck, StC has so many non-standard designs running around that when exclusive characters based more directly on the game guys show up, it's incredibly jarring (though as Vector and his scientist buddies demonstrate, being the same species as a game character doesn't always mean you'll look like said game character).
Contrast something like RS-MM, where people like, say, Roll and the cosmetics-bot actually look like they belong in the same universe. I don't think anyone could point at the show and claim it was inconsistent in that regard (except maybe the angry game-purists, but we don't talk about them).
WITH ALL THAT SAID, I still love me some alternate continuities and the Sonic series is no exception. They all have their own distinct feel to them, which is generally one thing I look for in my third-party stuff. I just felt the need to ramble about character designs.
EDIT: Seems that "problem" was not the best term to use; I should've said something like "Why do I subconsciously compare the designs of third-party Sonic characters to those of the games', when I don't do that with Megaman?" The answer is still "Megaman rarely has issues with visual consistency (design-wise)".
I'm not actually THAT bothered by stuff like StC's exclusive characters; it's just that I tend to notice when something'd not derived from the same base, if that makes any sense.
