Actually no, we don't have to kinda agree on anything. I created those gifs from E3 footage, i've watched almost 3hrs worth of E3 Zelda footage and BoTW looks to be one of, if not the best Zelda game to date and the only Zelda game i've liked is Wind Waker. That being said, Horizon appeals to me more than Zelda and i find its combat more varied.
The reason why i say that is when dealing with a Boss like in the gif i posted, Zelda is more constrained to using arrows while in Horizon you can use different types of arrows, bomb traps, rope to tie it down etc etc. It could just mean that we haven't been shown different ways to deal with that particular boss in Zelda hence my conclusion.
On a different note, while we can compare anything, i don't see why both games are being compared.
It's perfectly fine for Horizon to appeal to you more. That's your opinion and you're entitled to it. But the reason I say we have to agree that Zelda has more
variety, is because variety is neither opinion, nor some nebulous concept. It's about the number of things we can do as the player, and the number of things that can happen because of the things we can do. As of right now, based on the information we have, Zelda has more options and more interactions, leading to more possible/emergent outcomes, and therefore, more variety.
You can fight that boss by shooting arrows at it like in horizon (Zelda even has different arrow types as well), or you can hack away at it with regular weapons, off or on horseback, or use bombs. Maybe go on a bombing raid from the sky via the paraglider, or like I said before, you can get crazy with the environment. Slam its face with a giant metal rod via magnetism, launch a boulder at it with stasis, whatever the hell you want.
And obviously if we're going to compare these things, we're not just comparing boss to boss, but the entire game. And from what we've seen Zelda has far more variety, hands down. Shield surf down a hill and launch off a ramp, pull out your bow and go into slow-mo, shoot a beehive to make one enemy run away, then shoot the grass with a fire arrow causing an updraft, then use your paraglider to gain height again, then fly over an enemy and bomb them, then create more fire, glide up again, then do a falling sword strike on an enemy for critical damage. The enemies are defeated before you even touch the ground. Run around and collect all the weapons, and then the guy who ran away from the bees comes back to find his outpost destroyed and no weapons for him to use against you. He picks up a rock and throws it at you, and you smack it back like a baseball, hitting him in the face, toying with him. That's just one relatively simple scenario based on what we know of the game.
So yeah, I agree that the games don't
need to be compared at all. I'm gonna play both of them because they both look fun. But if the comparisons are already being made, then yeah, I'll jump in and defend Zelda's clearly superior combat variety.
