That annoys me, too. I am really tired of coming across that headcrab creature - the one that looks like a brain with tentacles and hops around? Not only do I see it in every new playthrough, but I see it appear in the videos of others as well. It seems like certain assets are not procedural but hardwired into the game. Given some lore, that would be fine with me. For example, maybe the headcrabs are a galactic nuisance that needs to be exterminated. Something like that. But right now they are just annoying.Unfortunately there's still a sense of repetition that crops up surprisingly early. I sometimes think the game had more variety in the early days, and for some reason HG scaled back that variety. For now I'm using Panspermia as my headcanon to explain why I'm seeing the same plants on multiple planets.
