Oh man, there are so many things that can kill you in an instant. Temperature is just one of them. This game can be very humbling at times, and we've only just started.
I'm in the middle of part of the story line that requires you take a trip up some very rainy and very rugged terrain towards the east, right to near the edge of the map. The word 'epic' doesn't even begin to describe it. It's going to take aaaaages to see even 1/4 of what Hyrule has to offer this time around. People have had to be very patient while waiting for this game to come out, and now we know why it took five years for the Zelda team to craft this thing.
I'm putting big 3-4 hour chunks of time into this. It's nearly 21:30 now on a Saturday and I haven't even had dinner yet. It's been six hours since I've eaten, my eyes hurt, my spatial reasoning (the bit of your brain that allows you to remember locations of things) has expanded immensely, and I've not had a single drop of alcohol. WTF? Time to rectify this.
I am a massive Zelda and Nintendo fanboy so I'd be addicted to this game anyway, so that kinda makes it sound a but weak when I say I'm addicted to it. But believe me, I'm addicted to this game.
