I hope much of this discussion is just translation issue, as translating distorts meaning a lot, in both directions. But your rudeness and insults are just not needed. Be polite or get lost.
You accuse me of not providing evidence, yet the link provided the evidence for my claim. Did you not see that it was a link?!
And do you even realize how the blue names in that screenshot read in English? What they mean? Visit this link to understand how funny the blue name for AI-made reads. Also "realistic" should read "real". And of course "space" has the meaning "космос" in the context of games.
Instead of admitting your lie (ignorance) about the 3d tag existing on Steam, you continue to attack me and shift burden of proof to me.
About half of these games or more, are on Steam and you would like to see them tagged 3dcg.
What a tag or category is, is dependant on context. Including the language. If you think a category is something that has to be exclusive, category is the wrong translation.
Instead of using single word terms, I should probably use descriptions, so you might understand what I am talking about.
I do know what 3dcg and 3d means. It is you who does not understand what the grouping by the word "3d" means on Steam or Itch. And it is you that does not understand that there is a difference between the meaning of the word 3d and the usage of that word as a grouping word. And you do not accept that the grouping by the word "3dcg" is just not popular outside of the sites you visited. Sites that use "космос" to talk about 3d games, I want to point out. I suspect how this translation oddity happens, but it is still funny.
And for the last time: 3d as a grouping word to attach to a game means only one thing: the people attaching the word had the opinion that the word was relevant. If you know who were those people and the context you can understand the grouping. There is a difference, if the publisher does it, or a site admin, or a vote by majority. You know sites where the people were admins. And now you complain that other sites have other people doing the grouping and not doing it the same way as those site admins you got used to.
