Well, the "curator" has got some biases that I don't share -- I'm not fond of 3D, in general -- but you have to expect that any game engine that's more accessible to newbies is going to be connected to more bad amateurish games. Anyone's first (or eighth) game is unlikely to be AAA. It's hard for me to picture someone just jumping into unreal engine, with no other experience, though someone probably has.
While there have been legitimately artistic pixel-art games, my rogue-like uses pixel art because I'm not a good artist. That's a cop-out, but I'm ok with it. I'm having fun, so I really wouldn't care if someone gave me a bad review.
Also, I tend to agree that godot's 3D support was sub-par up to this point. That's kind of the point of the big rewrite. So, it's not surprising that he's unimpressed by godot 3D games.
On the other hand, the guy was ignorant (last year) of how licenses work (not unusual, but still). And I don't understand his dislike of using free assets. How is that different from using an existing game engine, even unreal? It does reinforce what I've said before -- art is the most important aspect of game design, because that's what gets noticed first. Bad code can be excused; bad art cannot.
