BotW completely changed the open world landscape. Yes it was a bad Zelda game, it was by no means a mediocre game. That first experience is fucking magical, and has been recreated to great effect in Elden Ring and Genshin Impact (I shouldn’t need to point out how popular both of those games are).
You can dislike that it was a bad Zelda game. Calling it mediocre is just patently false. Granted, yes - I’ve called the game ‘Horizon: Zero Awards’ because it definitely should have won at least something. However, it was not more impactful than BotW.
All I have to say is that I sincerely doubt that From Software and MiHoYo were looking at H:ZD when they made their very successful games. That’s my only point, you are allowed to have your opinions about H:ZD - I’m not saying that you’re wrong.
