We "fall" for that because we love those games and sometimes the upgrades really bring out the best possible version. Sure, StarFox 643DS was not the best version but Ocarina of Time 3D was by far the best version of the game and a much more complete experience.
I played the game and it feels just like the original... which is a bad thing, paradoxically - it feels like it's a 14 year old game. It feels old, unpolished, dated. That's not how good remakes are made. A remake is an opportunity to reinvision a game - if their intention was adding slightly higher-res textures and slightly better models, they could've ported the original and it'd take less time to develop.
Metal Gear Solid: Twin Snakes was a complete remake of Metal Gear Solid for the Gamecube - it featured sparkling new models, higher resolution textures
and new game mechanics such as First Person View borrowed from Metal Gear Solid 2. If
felt like a brand-new title which merely shared the story of the original - OoT3D is nothing like that, it feels dated and has barely any new content in it. Look at how great HeartGold and SoulSilver were - that's how you make a remake. Everything was brand-new and it
felt like it. The price is also a problem here - if your game is going to be straight-up the same as the original then adjust the price to reflect that.
And Wind waker arguably has a bunch of flaws that, once fixed (and they will as they already did as shown in some gameplay videos where at least some of the flaws were adressed) it could very well be the best 3D Zelda.
You can't fix the entire art design which I personally hate, but hey - that's a matter of taste. Some people like it, some hate it. I'm more of a TP/SS person.
It is true, its cheaper to develop those games than new ones but i wouldnt say we fall for it. If people buy it obivously they want it, so why not make it? As already stated in another thread, its all about diversity and that includes remakes. Better than the same COD or FIFA game every year...
Remakes and ports the way OoT3D was made are not introducing diversity, especially if they're poor. They're the equivalent of serving an old, reheated and greasy burger - not only you've already tasted it, it tasted
better when it was new. As for yearly COD releases, at least those have sparkling new content in them - something I can't quite say about OoT3D, Starfox3D and knowing life, soon also Wind Waker U.
