The lack of PVE kills it for me, but it's a really fun creative game. Build a cool thing, smash it, repeat.
Try Empyrion. I was a Space Engineers player who has switched entirely to Empyrion. It’s SE with way way more complexity. Food and starvation, recipes, mobs, biomes, and so much more. It’s a criminally underrated game.
Is the game still being developed? I bought it in pre-release and haven't looked at it in years.
Yeah, it recently hit 1.0. They're also adding some things they said they wouldn't, namely more PvE stuff. I'm hoping they add NPCs of some kind with scriptable behavior to give us something to fight
Though the physics strains to keep up with more complex creations/scenarios, I have had great fun building big ships and then smashing them into things (or each other). It's another game where they give you a sandbox and the possibilities are up to you
They even give you a super-threadbare programming environment with which you can write C# code
