@Ace66062 @ceruds @JapanAnon @BackupHitter Roughly, yeah. It's actually only a year younger than Minecraft, as a funsies. It describes itself as a game engine and that's reasonable. There are mineclone2 and mineclone5 that try to full replicate MC gameplay, minetest itself is much more basic. I think it has furnaces? But doesn't have plant growth or anything.
Then I'd like to draw your attention to Urban Terror, Din's Curse and Sins of a Solar Empire.
