Subnautica is really fun, agree. Not many bushes in it though. Still need to get around to buying the 2nd one.
I really enjoy The Long Dark. You can't really craft your own structures, BUT it has a lot of depth to the survival elements of its gameplay. Changing weather, getting colder if you're wet, changing wind direction, that sort of thing. I find it relaxing on lower difficulties. It is stressful 'til you learn the basics of it but it has a LOT of customization for difficulty settings. You can turn off hostile animals, tweak the amount of loot in the world, and so on. I found just putting everything on Baby Mode while I learned the basics was helpful.
Generally, you scavenge for food, resources, warm clothes. There's a variety of wildlife to encounter. Lots of things to craft. You hunt, explore, and so on. You can set traps and fish. Boil water, cook food, day to day stuff. However, it's also more desolate winter environment than a lush, green forest. Very pretty though. Nice sound design and ambient music. The Aurora nights are gorgeous.
It's really rewarding once you start memorizing where everything is and using landmarks, and figuring out how to get by day to day. It has great art direction, too. There's a Story Mode they are releasing episodically, which I always recommend to newer players because it has Checkpoints. The base Survival game doesn't have Checkpoint, but if you die in Story, it won't reset your entire run. I don't think it's unfairly hard, but dying & losing runs is definitely part of the process.
The other one I like is The Forest. It has some creepy enemies, but you can tweak the settings and play on peaceful mode. You can build structures, need to gather food, water, and that sort of thing. Lots of chopping trees & building things which is kind of bushcraftesque. Lots to explore on the island too, if you aren't put off by horror elements. Even with enemies turned off, a lot of the environments are creepy. I think it's more a "bushcraft if you squint" type game. Wouldn't recommend if you can't stomach horror games though, generally.
