They should have made something new instead, YL are mediocre characters in a mediocre Universum. With new characters and a new 3D platform game in a new gameplaystyle could be something to look forward to.
Couldn't the same be said about Banjo Kazooie then? Since Yooka Laylee is pretty much a BK game reskinned lol. Besides, they've already given them a new playstyle with Impossible Layer being a 2D platformer akin to Donkey Kong Country. The way I see it they've got proper financial backing now, so a new Yooka Laylee won't have to take shortcuts and whatnot like the original which was crowdfunded.
