Honestly yes in graphics and artstyle, and the "feel" of the world, Horizon looks miles better.
Sales... yeah the PS4 userbase is alot bigger than the Wii Us.

Metacritic scores? that one is still up in the air.

I agree, except for Metacritic, Zelda being an old licence, it will automaticly get +90 just by the name as long as it's decent. It's like Mario, it automaticly gets better than it deserves ( and even nintendo fans will agree with me that NSMB Wii U should get less than DK C WiiU )

While Horizon will likely be around 88-90 , new IP from dev who never made an open world

Zelda U vs HZD PS4

I'm going with horizon to sell more
I'm going with horizon to trounce it graphically
I'm going with Zelda U to have a higher metacritic

It will come out on the NX too so I reckon that could push total sales in Zelda U's favor but graphics still horizon.

Strange comparison considering its a new IP. Uncharted 4 vs Zelda makes more sense.

Also lol both these games were meant to be out already. It's funny when you think about that.

Were they? I thought HZD was always supposed to be a 2016 game?

hmm isnt horizon an rpg? anyway Ill go against the grain and say zelda wins meta and sales and horizon won't live up to the hype

Super Mario 3Dworld is where deserves to be at 93 though, same with Mario Kart at 88. And Mario Galaxy 1 and 2 were also where they deserve to be, so you are making a rule out of an exception, and not a big one because 84 is not a +90 yet the game was decent as you say, and New Super Mario Bros 2 on 3DS has a 78, getting a big score just for the name uh? 

I could see Zelda doing better on sales. Seeing as 1st party titles do so well on the system, and people really want this type of Zeda (except for the graphics), it might sell really well.

Now, it's really hard to tell where Horizon Dawn will end up. I looks like a fantastic game that PS4 owners will eat up, but is there anything we can compare it to? I'd say it sells at minimum 1.5 million units just because it looks like an attractive game, but, again, I have no idea where it would end up on sales numbers.

I don't really care about the 2 other categories. Of course HZD will have better graphics, and metacritic is just a bragging rights number. Kind of useful number, but no reason to compete with others.

Graphics: Horizon > Zelda
Sales: IF PS4 vs. Wii U--> Horizon > Zelda
If PS4 vs. NX/Wii U--> Zelda > Horizon
Meta: Zelda > Horizon
Art style: Subjective

Better game!?

You know that ever 3D Zelda game is always one of the best games of that generation and that Zelda U looks like it will be one of the best Zelda game ever!?

We are talking here about 3D Zelda, and worst score for 3D Zelda is 93 for Skyward Sword.
