Chinese alternatives do not feel safe/convenient even for someone like me who speaks both Mandarin and English. Note that some local services cannot even be accessed overseas without reverse proxy or something like that.
So far my personal experience (currently located in that zone of limited internet) is that streamyard has yet to be completely blocked (but if the service uses anything that requires Google or another blocked service in the backend, those will cause connection issue during play). It’s only a matter of time before they also get banned, so I’m using it as much as I can for now.
Even with some help from (imperfect) proxy magic, people who have played with me here know I will disconnect at least once during play (not always due to censorship, but a combination of technical issues), but because they’re patient we got through the games. My storytelling ability suffers due to the unpredictable technical distractions, but I tell myself that I’ll improve over time once I stop needing to double-check the rules (aka one less cognitive load).
Play-by-post/chat would be great for more nuanced wuxia storytelling (enough time to do some research or use clever puns before putting words down), but it’s so easy to lose motivation if the group is not already devoted to either the genre or writing a story together for an uncertain amount of time. As for synchronous play-by-chat it still tends to take longer than video/audio-chat because we tend to want to edit more.
p.s. I might sound like an apologist, but I want to believe that it’s not all about censorship to freedom of information in all cases, but probably has an element of protecting local industry in the same field against foreign competitors who had a head start. In the future it’s not clear which giants in the industry of which nation will win out, but for now I personally prefer certain styles than other types when it comes to web services; it just happens that many of those services are blocked (throttled to the point of unusable) where I am currently.
