New Zelda, "Breath of the Wild" demo looking pretty awesome.
Gameplay highlights:
-More survival style. Cutting grass no longer wields goodies. You need to eat food to recover health (you can also cook raw ingredients for better food), starting weapons and shields wear down fast so you need to always be looking for replacements.
-More melee weapon variety! Axes, clubs, spears and swords besides bows and bombs.
-You can climb pretty much every surface to reach new places, although it drains stamina faster the harder the surface is to climb. Also shield surfing!
-Very dynamic world. You can chop down trees and then roll them down to create improvised bridges or squish enemies below. Weather changes, like rain makes it harder to use fire stuff, while lighting has higher chance of hitting anybody using a metal sword. And you can throw a metal sword for an enemy to grab so that they're hit by lighting. You'll also need appropriate clothes to avoid losing health in cold/hot enviroments, with different degrees of cold/warm (like as you climb a mountain it gets colder and colder). Enemies hang around in bases, sleep at night and you can steal their weapons (that last bit isn't exactly new as you could do it on Wind Waker, although you couldn't take enemy weapons far). Plus set plants on fire.
-Real open world this time. You start in a big field and then can go wherever you please at start just like in the first Zelda. 100 shrines to explore!
Plot seems to be that Link was put in stasis sleep and when he wakes up Hyrule has been reduced to ruins (the demo allows you to poke around the remains of the Temple of Time among others). Lots of clues pointing out to "Ganon did it". Excuse me, Calamity Ganon. Also Sheik stuff. There seem to be other towns, but they weren't shown in the demo, saying they're a key part of the overall plot. So I would guess Link's job this time is to rebuild Hyrule.
