Yoshi's Story is a woefully flawed game, Yoshi's moveset from Island is, IMO, too complex to work in a beginner's game; the save system is somehow worse than even Crash 1; you spend most of your time being bumped around uncontrollably; it's impossible to play every level in a single playthrough; and it had a rather negative effect on the perception of 2D games at the time of its release (not that that last one was its fault, but still), but it's also a game I can't bring myself to even dislike, let alone hate - mostly because it was the first game I ever beat, but also because the artistry of the game's visuals is just incredible, and I appreciate how it continued the experimentation of Island, even if not to nearly as good an effect. I'd also argue that it has one of the best endings in a Nintendo game.
