If its in their own trailer, its fair use. If they use it to sell the game, its fair use.
But ok, I'll pick the better looking gifs.
These aren't exact comparisons, but close enough.
Avatar on top, Horizon below for every comparison.
This video isnt even from Burning Shores, its from the OG Game. Still punches up.
And then in Horizon you have an entire underwater world to explore also that looks just as amazing.
Not to mention incredible Lava
Semi Destructible environments (Trees, small structures, etc)
Vastly superior character models and animation.
And certain "small details" in the game just are on another level.
NOT to mention, Horizon also has by far, the most detailed enemy character models in a game (the machines are rendered with an INCREDIBLE amount of detail)
The NPC's look better than most games main characters.
How is Avatar better? What are you guys talking about lol.
