How is it superior? Is it approachable for kids around 7yo?

yep vintage story is fun

I tried Minetest a while ago and was never really able to get into it. The new player experience was rough, a lot of decision paralysis. The texture style can vary between mods and servers. It didn’t feel very cohesive.
I don’t know if that has changed since I last played, but to me it didn’t feel like a minecraft killer then.

From what I can tell, Hytale was supposed to be a bit like Terreria in 3D, as well as a platform for minigames. The gameplay and graphics from the trailers looked really good.
I’m sure it would have been a Minecraft killer for some. (Ex. players who primarily play for the minigames like bedwars)

The irony of these projects is that they only seem to appeal to people who don't really like Minecraft, or used to like older versions but not recent ones. They have zero traction among active Minecraft players.

I've tried most of them and honestly they don't hold a candle to the original - not that they are bad games, but rather they entirely miss the point of modern Minecraft and why it is so appealling to so many people. Although (some vocal fraction of) the community likes to nitpick every single detail of every single update, it is an incredibly well designed game.

I love reading a basic text article on the modern internet...

Holy shit...

Minecraft

Well designed

That would be a long list but here is something that everyone can notice in the first minute.

It loads and you are actively playing in a world before Minecraft even finishes its loading screen (I have seen Minecraft get stuck on a sync with Microsoft screen for 30 minutes with no option to skip the sync or do anything else to actually start game play).

It can but it doesn’t need to. The out of the box experience is better and the mods can do more fundamental changes to the gameplay experience.

Hence superior

"Privacy"

I think so, yes. Although I dipped out of their blogposts around the time they rented some big office space. That was years ago at this point.

it's about the pixel-art and the cubes, am i right ?

There is also Veloren that is free, open source, and looks pretty good

I'm disappointed, but not surprised... I have followed since the first announcement and gave up hope around 2020. Every dev update was "we made 1 step forward and 5 back" with no real substance to show for it.

Assuming the trailers are real gameplay though, it looks like they could have and should have released an alpha years ago. Not sure how they thought it wouldn't work as Minecraft released in pre-alpha and it worked out in the end. A shame we'll probably never see the code or even a compiled build from all these people's work.

Minecraft has many issues unrelated to the game's visuals, some of which have only received somewhat unsuccessful band-aid fixes (notably, enchanting+repairing mechanics)
