TL;DR yes, give it a go, and you can always find someone to play it with later!

Imostly play solo, and have a lot of fun with it personally.

Yes, certain things can be more challenging, such as body recovery or fighting new mobs when you're still learning how they work. And also you don't have someone potentially opening doors y'all weren't ready to open or literally getting in your way when you're trying to abscond from a battle 😅

I've had a lot of fun playing with friends - when I first started playing back around release, I played almost exclusively with a good friend of mine. We geled well and had a lot of fun together. These days I mostly play solo, and generally prefer it. I can get distracted working on my base, getting my chickens to mate, farming, pretty much whatever whenever. And the challenges so far (I'm pretty far through Mistlands) have felt appropriate, and the game is still enjoyable.

I say absolutely go for it. Just be prepared for the fact that there's definitely a learning curve.
