I'm in China too. I have to have my stuff shipped to family in the US and they send it to me here. Where are you at? I'm in Chengdu.
I've been assembling models to pass the time because of the virus lockdown; I'm painting today. However, its been a while since I've played. I play with my girlfriend from time to time, and I used to play on Vassal with a friend in Korea. I'd love it if I could find a group here or even start one, but its easier said than done.
The app is amazing and I'd highly recommend it. With the app and the rules you could play on Vassal to test out the new system. One thing I've had issues with here is finding primer. You can get Tamiya primer online but I've been using Dutch automobile primer. You can get GW primer from Shanghai or Hong Kong, but its not easy.
Out of curiosity, what is your plan for starting crews? Teaching it to my girlfriend, I've found that some are better than others for beginners if you plan to bring players into the game. M3E has a bit more bookkeeping than M2e as a lot of Masters have a signature skill that relies on unique tokens, but the new conditions and consistency of named actions and triggers across models is great.
