We all know about the Nintendo tax and how much more Nintendo charges for older games than other companies. The Wii U ports have been a prime example of this, and there are plenty of others. Even still, $60 for Skyward Sword HD seems like a lot compared to recent trends both in the industry and at Nintendo.
Remasters and remakes have been a trend in games for quite some time, and there have been a recent spate of high profile and, at least in my opinion, high quality projects. We got Crash, Spyro, Crash Team Racing and even Tony Hawk 1+2 Remakes from Activision, and they were all excellent and all reasonably priced. The Tony Hawk games totally remade with the old soundtracks almost all there AND new music, which couldn't have been cheap, was an especially impressive and compelling package, at $40. Sony has been consistently remaking old games and pricing them anywhere from $40 to much cheaper. Microsoft offered the Halo Master Chief Collection and the Rare Replay Collection, both of which are among the best deals in gaming (at least now that the MCC works.)
Even Nintendo has improved recently. Yes there was the Pikmin 3 port, but that had some enhancements and was an already modern looking game from an obscure system. The Mario 3D All Stars collection may have been bare bones in terms of the games offered, but did provide 3 classics for $60. The recent Mario 3D World port included Bowser's Fury, which many people wish was a $20-30 stand alone title...showing that it has serious value on top of the already excellent 3D World.
Skyward Sword may be getting more substantial updates than just an HD sheen and updated controls. Maybe there will be some reworked textures (they did that for Mario 64 in the All-Stars collection) and they might even do some of the stuff they did with Windwaker in terms of streamlining and fixing some of the design issues, but even still it's a high price for an old game that clearly is not getting the full remake treatment.
There's also the fact that Skyward Sword is widely considered the worst mainline Zelda. I'm sure Nintendo doesn't think about it that way internally, and they seemed defensive in the presentation, saying that it helped pave the way for Breath of the Wild, but it's definitely a factor.
I know there will be a lot of people saying "it's Nintendo what do you expect?" and "it'll still sell well" and, yeah, Nintendo likes to do this (though they've been doing better recently) and it will probably sell decently (though Skyward Sword on the Wii sold under 4 million units, which is not great for a Zelda) but...it sucks.
I think that playing Mario Galaxy on the Switch has made this extra disappointing for me. Because that's another Wii game, widely considered a much better game, which is also from a major Nintendo series, and it came packaged with 2 other mainline Mario games. People complained about Mario 3D All Stars as a value proposition, but...well....
And again, Mario 3D World, which was just released, came with a brand new adventure that some people are already saying could be the best game of the year.
I wonder if they planned to do a Zelda Collection but covid messed it up. Even still they could launch this at $40 as a stand alone. $60 just seems like a lot.
