The point isn't that people can communicate over the Internet though. That's easy to explain.

What's harder to explain is the emergent behavior that comes from that. I like to think of this as "meta gaming".

Generally when people start playing a new game, they don't care much for picking the optimal team/items/tools, they just play to have fun. As they play more, they recognize that some combinations are stronger than others. Some people will theory craft those combinations.

Over time, the general population will inherit those combinations, or perhaps build against it. That's kind of like the Internet before and the Internet now, but on a much larger and more complex scale.
