IMO, BOTW would have been
way better if the second screen Wii U features were left in. Part of what makes the game too easy is you can just pause and eat food at any time. If you had to look down and pick food while a Lynel is trying to kill you, the food would have been less game breaking. When I play through it now, I purposely underprepare to make it more of a challenge.
Yes it did. The fact that the Wii U didn't even sell 15 million units kinda says it all. The gamepad gimmick was shit and the marketing was shit. It was so shit that it killed Iwata
If you make an argument that sales correlated with quality, you are essentially making an argument that BOTW is far and away the best game in the series, are you not?
In all seriousness, the Wii U itself was fine IMO. Not great, but fine. The gamepad was comfortable, it worked well and the library of first party titles was pretty good. I'd argue the first party output was better than the Wii based on the Zelda remakes, Splatoon, Mario Maker, Mario Kart 8, BOTW and Pikmin 3 alone. It was never going to sell as much as the Wii because that was a fad that a lot people who don't usually buy videogames scooped up. However, I think two major flaws kept Wii U back from selling 25-30 million units(basically N64/Gamecube territory):
1) The Wii U had a decent GPU and ram for the time, but a real shitty CPU. Nintendo got around this by offloading most of the work to the GPU which is why first party Wii U games by and large look pretty good. However, third party developers really struggled with it, meaning multiplatform titles that came out for 360/PS3/Wii U hit a bottleneck with the Wii U's CPU so they really chugged compared to the 360/PS3. If this weren't an issue, the library would have been padded out with more multiplatform titles early on. PS3, 360 and Wii U actually all used Power PC CPUs, so quick ports of things like Oblivion, Skyrim and GTA IV & V
should have been easy if it weren't for the CPU.
2) As you alluded to, the marketing early on really pigeonholed it. Nintendo didn't make it clear enough that this was a "New Wii" as opposed to an accessory. It probably should have been marketed as the home version of a DS with more 3DS cross play features.
