In context it seems like the “play your games with friends” part of your comment is what they were getting at, and less about the forums and such. For me at least, that’s a big draw. I’ve hyped remote play together a lot, but it’s a huge reason I prefer steam. I can also share my library with several other people, so buying a game there is like buying it for a few of my friends too. I think that’s the stickiness he’s referring to.

But Steam also had friends lists, messaging, playtime stats, and those little popup notifications about what your buddies were playing. “What Steam did better than anybody else was to create a community,” Kuperman argued. “They established a stickiness to it, that people came back because it was Steam.”
