The “which one” was in reference to the original comment. Which was about Epic.

So we were talking about epic. Glad we cleared that up.

Dictionaries generally (because each one is going to have a slightly different definition) define it as having complete control over a market.

So it's not a Monopoly then.

Whereas a lot of the monopoly laws and departments define it as having over a certain percentage of the market share, even if it isn’t 100%

And seeing as Valve appears to not be running afoul of these laws, not a Monopoly then.
