Rumor has it there's an HD port coming to PS4/Switch.
But in all honesty, I'm of the opinion EM would've been better served as a film than a game. The core concept is amazing & is probably the best plot Disney could ever come up with for a Mickey movie. The gameplay ideas, however (both the moral choices & the general platforming) never felt fully realized. & then there's the sequel that did everything worse: smaller-scale plot, shorter length, AI is too incompetent to make single-player enjoyable, but co-op has its own issues.
Also, while a world of forgotten Disney characters sounds interesting on paper, the execution of it is head-scratching. Smee is a forgotten Disney character? On what merit was that decided? There's also a bunch of different Petes, oh Pete himself isn't a forgotten toon, but alternate versions of him are? God, what a cop-out. How many alternate Mickeys are there in that case? Prince & the Pauper just off the top of my head.
Heck, Clarabelle Cow & Horace Horse are borderline as I was vaguely familiar with them prior to their appearance in KH2. Which, oh yeah that's right, some of these "Forgotten" characters had already appeared in KH before EM, which should've been an instant disqualification from Wasteland membership. Heck, KH actually one-ups EM with Clara Cluck, a character I actually never did hear of before KH2 & is not present in EM series.
Another thing KH has over EM, acknowledgment of the origins of all the characters. Jiminy's journals breaking the 4th wall to point out what short/film each character made their debut & what year. EM is filled with tons of references but fails to have any sort of codex to explain said references despite them all being obscure by design.
Other forgotten characters that didn't make it include Dumbella/Thelma (Della's original incarnations), Mrs. Goof & Goof Jr. (Goofy's wife & kid from old shorts, & Amelita/Felicity (Mickey's sister). There's probably loads more comic book characters that could be dug up if I were to continue digging.
