There’s builderment, that is kind of a simple factorio but without creeps (or main character for that matter)

Mindustry and Shapez IO (browser) are pretty good.

I had forgot about Mindustry...

What have you done to me! Loved that game and wasted way too much time on it, will have to spend some more.

Edit: Looks like it even got a fair few upgrades since! You can even code in game now.
