It's not, China's great firewall don't block all foreigh servers they only block a few, it's more of a distance and internet infra problem. Not saying it's indie game's fault but it's true very few indie games have online multiplayer and very few really made it awesome, most of the time networking is not worth it for smaller games, a lot of awesome local multiplayer games won't even consider online. And yeah strategy/turnbased games definitely will be better.
