I've been curious about Lethal Company, but I'm not a streamer and I don't have friends to play with.
That said there's another game almost identical to LC called Murky Divers and instead of going around different research stations on different planets, you're cleaning out research stations underwater.
You have a sub that you use to go around the ocean, and there's like a radar to help you navigate, avoid creatures and obstacles, and find locations to actually go into. There are all manner of creepy underwater creatures and anomalies to find/avoid, and I'm sure there's at least one giant sea creature that can come and fuck you up if you're not careful.
Tbh I didn't get very far because as soon as I pulled up to a location and got out of the sub, I freaked out and turned the game off. I ended up refunding it because, again, I don't have friends to play with and I'm not a streamer lol. But it did seem like an interesting spin on the concept.
