Initial impressions are good. The translation is definitely one of the best Chinese->English I've seen, with maybe only Gujian 3 being better. I've only played a little, so I can't comment too much on gameplay, but the game seems like an interesting mix of Mount and Blade/Kenshi, with action-RPG combat somewhat reminiscent of Diablo 2, but definitely with more emphasis on positioning and movement (IE - quite a lot better, imo), and a bit of Musuo-type games. There seems to be a lot of variety in starting classes and a fair amount of freedom in building out your characters from there too, with trainers scattered around the lands and skill books available for acquiring and purchasing. The setting is great, I like the environmental and character artwork a lot, and the music has been very good so far too. It's a really unique experience, is about the only way I can sum it up right now.
I'm playing "Expert" mode with one of the "Normal" difficulty starting classes to see how far I can get. Expert mode is essentially a anti-savescumming mode with a single save, but not quite Ironman from what I can tell. Nothing too crazy challenging in the first couple hours, but I did almost die about 2 times.
EDIT: Nevermind, as I venture out further into the gigantic world there is to explore, I'm getting my ass handed to me more and more. A very good sign indeed. Also starting to notice a lot more of the world simulation that's occurring around me, with things like notable NPCs joining and leaving particular factions, special bazaars springing up, times tournaments tied to faction favor starting here and there. Very cool!
