How to promote an online game PC end-game platform?

Under normal circumstances, we want to promote an online game. If there is a platform on the PC side, then we must first launch this product for some people to use. It's just that some people feel particularly good when they come to use it, so they can continue to promote it. After the promotion, more people will know that when everyone feels better, more people will pay attention to this platform and more people will join in. So the best way to promote it is to experience it first and then promote it.
