It's astounding to me how folks can see two blocky games and immediately bite into hype and equate them to being the same thing - and thus worthy of having one of the two dominate and kill the other. it's fanaticism at it's finest.
Minecraft served it's purpose as one of the original sandbox survival games. It's casual, not too complicated in it's mechanics and nowadays people mostly play it for nostalgia as the devs have shown they don't want to stray from it's original experimental formula that is now set in stone, it is not likely to mechanically evolve in any meaningful way in the future.
Hytale was the natural response to a highly profitable online server within Minecraft wanting to grow and branch outwards. I suppose the owner of said server wanted more autonomy because earning money within another entity's videogame is a liability. They have stated frequently that their focus is on player made experiences, and their curated singleplayer experience was going to be non-procedural, a custom made adventure map from Minecraft, if you will, aside from featuring a creative mode that would use procedural terrain for it's world generation. If you look through it's now released internal development material it's quite obvious it wants to be another Roblox. In my opinion it makes a lot of sense if you look at their origins. The original owner of Hytale was running a highly profitable server within Minecraft and was making millions and wondered how much more they could make if they had their OWN game of which they were in charge where others could make their own profitable servers within instead. Currently, Hytale is a copycat from Minecraft / Terraria / Enshrouded within it's designs and mechanics, it is not new or innovative in any meaningful way and like someone stated before has currently been released as a 4 year old dev build now finally being updated together with it's newly re-acquired community. Hytale currently features no drastically different mechanics from it's source inspiration Minecraft, other than it's much more clear focus on RPG style combat mechanics.
Vintage Story on the other hand was quite clearly born from the desire to create something new and innovate, as Tyron was quite clearly much more creatively inclined than he was allowed to be during his time with Hytale. From all of the custom mechanics Vintage Story displays such as Smithing, Farming, Cooking, Leather Working, Weather Simulations and more it's quite obviously not a competitor to either Minecraft or Hytale, it merely borrows Minecraft's large voxel-style terrain generation, which had already previously existed even before Minecraft to be fair.
None of these games are going to make the others obsolete, each are very distinct and unique games in their own right, though I will personally add to this that my original hopes and visions for Minecraft back when it was being updated was what Vintage Story is today. I had always hoped for a much more in-depth approach to survival and the real mechanics of the world, and after having spent thousands of hours in Minecraft I personally doubt I'd return to it any time soon.
