так и не осознал, что хранится в БД, а что - в RAM ... автоматические системы кеширования/сброса в БД?
Как, собственно, производить синхронизацию клиента и сервера?
создавать на клиенте экземпляр той же симуляции мира, что и на сервере
может ли что-нибудь дать использование ASP.NET (возможно core) в качестве основы, или для таких целей его использование бессмысленно?
