I had fun with it. Can be a bit slow and grindy, as forming a build involves finding the right (randomly generated, periodically refreshed) techniques and studying them. And there’s a big power jump in each area so this process has to be repeated regularly.
I initially got into it when looking for something like Wandering Sword, but as a M&B- or Kenshi-style open world, which it’s not exactly that.
I haven’t.
The Matchless Kungfu certainly looks like Wuxia Kenshi, but I haven’t actually gotten around to trying it.
