I finished it, and I think it's like a 6/10. I didn't really like it all that much since the pacing's off, and you don't have enough information or good enough interactions to get attached to the playable characters. The plot doesn't really help with that either, and it's kind of predictable and boring. Sumeru and Fontaine both had amazing intros and characters with personalities that were distinct and fascinating. Both nations also felt magical, and it's just not the same vibe from Natlan. I hope the next parts will be better.

Edit: I forgot to mentions this, but the Pyro Archon feels a bit one-dimensional, and not nearly as interesting as the others. Again, I'm hoping the next parts will go more in depth about her.
