Oh, I agree it's great! It just constantly reminded me of Journey, a game that I still think about (and listen to the soundtrack) with great regularity, which I found a little distracting. It's still highly recommended!
I'd be fascinated to know what someone who wasn't familiar with Journey would make of it.
Sword of the Sea is very good, but it feels a bit like someone trying to make Journey: The Video Game.
It uses actual (admittedly poetic) English text to describe the history of the world, which is much less mysterious than Journey's heiroglyphic iconography, and I don't recall anything in it being as surprising as Journey. It has high score challenge levels, and

I had fun with it (and am enjoying hunting down all the hidden bits in NG+), but it isn't as special as Journey was, a fact it repeatedly reminded me of by attempting to evoke so much of the same imagery.
Definitely want to take a look at Indika next, I've been curious about it for a while.
I'll admit to a curiosity about the Ireland expansion, but I'm not much bothered about the rest. I'm generally happy to hop in and out of things, and I've never really been much of a completist.

Nothing appeals to me less (unless it also involves deck building).
I got a bit bored of Mirage after a while and wandered off, but I've just started playing Valhalla. I wanted something big to wander around in, where the world wasn't necessarily immediately hostile to me, and so far it's fitting the bill okay (though I've only just gotten to England, so maybe it gets A Bit Much in the not too distant…). I am wondering about going back to Baghdad once I've had enough Viking-ing-ing, though.
We watched an episode or two, and I wanted to like it, but the whole thing felt a bit am-dram.
EDIT to expand/clarify: I mainly think it was quite poorly directed. There are some good performers in there, but not many of them give very good performances, and the editing isn't well-paced, so it all runs a bit baggy. And the plot (what we saw of it) was only slightly more nuanced than, "From my point of view, the Jedi are evil!".
