Nintendo, here's a great improvement for Twilight Princess HD : how about waiting until after Zelda U releases? Bar Hyrule Warriors and Triforce Heroes, all Zelda games thus far have been remakes. I want a new game, not another remake.
But let me get back on topic. Things I want to see in TPHD...
• Dem Wii U Tech Demo Graffix, plskthx.
• Add some colours into this game. All the browns blended in too much and made the original look dull and bland. It was especially difficult to look around at night.
• Please Nintendo, for the love of all of, please fill Hyrule Field with stuff. More enemies, more secrets, more everything. Don't make another barren, empty overworld.
• Miiverse integration. I loved the system in The Wind Waker HD, and I think it could be used here, too.
• The horse whistle should have not been an endgame or near the end of the game item. Give it to us much earlier, like after escorting Prince Ralis to Kakariko Village. Ilia sees us riding the horse, why not reward us with the whistle along with the Zora armor?
• A fully orchestrated soundtrack.
• Make some of the dungeon items more useful, especially the Spinner. Outside of the dungeon you get it in, it rarely saw use.
• Maybe a few new sidequests?
I'll edit this post when I think of more.
