I am seeing people argue already about GOTG and all of that between these 2 games and I think it is impossible to tell.
I am a lifelong Zelda fan, and BoTW blew me away.
I have never played a God of War game before and I am currently being blown away by it.
But comparisons between the 2 wont really go anywhere. They are different.
Zelda was a pure open would romp. I could go anywhere I could see I could use anything I find to craft something and I could do something with almost everything in the environment.
GoW has some open world aspects to it, but at its core it is a story driven game. God of War eliminates the most annoying aspects of BOTW while not having 1 one thing that made BoTW groundbreaking. Zelda had a decent story, solid gameplay mechanics, but certain things were extremely unbalance or even broken. Food for one takes any challenge out of the game even on master mode. Weapon durability is a weak concept, it simply is not fun avoiding fights for the simple reason you don't want your weapons to break, the master sword alleviates this a bit, but still it is a constant drag. This to me is a major negative, maybe the only negative for Zelda.
GoW lacks the pure freedom of Zelda, but it also creates solutions to Zeldas main issues. Your Weapon does not have durability, and arrows are infinity (on a micro CD).
So one has a massive world where you can go anywhere and do almost anything (Zelda), and the other is restricted but has better balance and deeper combat. So basically
Zelda has an advantage-
More to do
Better puzzles and more of them (by a long shot)
God of War has an advantages-
Much better graphics
Better and deeper combat
Better story and story telling
Balance. (Zelda has this weird point in the game that it goes from being kinda hard to easymode, like really fast).
So as you can see each game has advantages, and they are advantages in huge areas. So depending on what someone is looking for in a game will make them lean one way or the other.
I am not done with GoW at this point and I really cant say which way I would lean. If GoW finishes really strong I will probably go that way, but many games are stronger early and weak late so if that is the case I would go with Zelda.
add me, the more the merrier.
