I have no doubt Zelda will be amazing, but this is the same shit you hear with every new Zelda release. People losing their fucking minds.
Horizon has absolutely nothing to worry about, in fact based on install base I'm willing to bet more people will be playing Horizon on March 3rd than Zelda anyway. Two completely different games, on completely different systems, and mostly completely different kinds of gamers, but yeah let's compare the two. Makes perfect sense that 50 million PS4 users are going to run out and play Zelda instead of the new hotness on their main console...lol. What a bunch of trumped up game "journalist" nonsense.
Honestly, outside of sites like this you're better off ignoring any Zelda discussion for the next six months until the fanboy worship dies down a bit and you can make an objective statement about any part of the game that isn't perfect without legions of mouth breathers going full assault on your ass. Zelda is one of my favorite franchises ever but I can't think of a community I loathe more.
