To me Hardcore game branches into various aspects due to genres and possible objectives.
In overall the essence of a hardcore gamer to me just means constantly committing 20hours+ a week of gaming. If you have enough dedication to your hobby then you're hardcore.
Now if we go into objectivity we have have the hardcore collectors, competitors, completionists, grinders, and explorers. Feel like I'm forgetting something else but oh well. All these types of hardcore gamers are still hardcore but in their respective ways due to the games respective genre. You aren't limited into just 1 subcategory though.
