Well he's racist, sure, but what he said in this tweet is true. I'm very surprised that everybody disagree with that. Or maybe it is because he is racist?
Anyway yeah games have been designed (the difficulty of the levels, the game design, the lenght, etc) by developpers to be enjoyed in a way, if you rewind everytime you fail or if you're using save states every 10 seconds in the game, yes you're not beating the game. And yeah it's not a big deal sure, but if they add a feature in a Dark Souls remake that make you insta kill every bosses, would it be "ok whatever enjoy the game as you want"? I don't think so.
Sure it's not a huge deal, sure he's a racist, but he's right about this.
