I honestly lost interest the longer I watched the livestream. I had plenty of time at work to watch it without interruptions and it just felt unimpressive to me. If this iteration had already been released as a Wii U launch title or 2013, I would have felt different. Now, there are so many openworld games that it doesn't feel inspired in any way from my perspective.
The whole Amiibo, bring an ally, seems like a straight money grab as well. I get it and all, but it jsut didn't sit right with me.
Nothing about what they showed felt like a real Zelda title. Sure, you had Link and a HUD and stuff, but where was the dungeon expo? Where were the awesome puzzles? Where were some concept item usage? All you got was crafting(every other rpg since Minecraft/Elder Scrolls), weapon inventory other than main sword(I know they been playing with this since Wind Waker but I never felt it belonged in a Zelda title), and some gimmick surfboard on your shield stuff.
As I watched the stream, I really thought I was watching SotC 2 with Zelda skinned over everything. To me, that isn't a Zelda title. I guess my love for the Zelda franchise begins at LoZ then ended at TP(even that felt a little too big at times). No issues with huge Zelda games in general but if trekking across a giant overworld gives you the feeling that your $60 was well spent, you might as well grab TES games for dirt cheap on steam and walk around out there.
That said, I will probably pick it up in a couple years at $20 to experience it one time to truly see if I will enjoy it. Too many other titles I am interested in this year.
