They tout motion controls and Fi as it being a shit show but one of those can be fixed and the other vastly improved upon. True innovation with 1:1 sword combat and fans hated it
See this is wrong, though, because those two things are
not the main issues people take with the game. While yes, the motion controls and Fi might have put people off from playing it further and thus they don't get very far there are people like me who had no issues with the controls and "tolerated" Fi still dislike the game a lot. And it's because Skyward Sword has a myriad of game design issues. Backtracking is a common thing the game does, not just once but more than once. Then, there's the awful fetch quests (which are abundant in SS)... and then there's the escort mission in the Eldin area (god this is actually not a fun part of the game), the tadtones, how swimming works (nevermind the fact swimming is tied to motion controls, how they make it work with them is frustrating), recycled boss fights in general (not only the imprisoned but also Ghirahim), the Stamina Meter is completely arbitrary, etc. There's a zillion issues with the game from a core level that for someone like me to like it (which there's a good portion of people who feel the same way I do) they would have to completely overhaul the game.
The point I'm making is that those two things you stated are not the only issues with the game and if that's all they do to "fix" it, they aren't winning back people like me. Nor do I expect them to fix all of those things I listed above anyway with something in the scope of just a HD re-release or even just in the scope of a Wind Waker-style HD re-release.
I really wonder if people who hold SS so highly have replayed the game in the last 5 years. Or, even seen the game recently. I remember all these very bad parts of the game over anything the game did well and I played it when it came out. Meanwhile the dungeons people praise as the best part of the game are
completely forgettable to me. I only remember the two Desert dungeons because those are the only two that actually stand out and probably the only two parts of the game I actually enjoyed for the most part (barring any backtracking and/or fetch questing at that part of the game). Well, except probably the overworld part of the desert (that area is
not fun due to the stamina meter I talked about above).
I mean, if you like the game that much despite all these flaws alright you do you. But to me, SS is worse than TP and WW because it uses up so much of your time to open up areas more by having you do
extremely tedious stuff that isn't actually fun to play and only exists to pad the game out.
