I disagree. Casual is meant as something you do casually, not putting in alot of time. Being more relaxed, less stress. Hardcore players do sacrifice things IRL. You have to sacrifice something in your life to put most of your time into the activity that you are hardcore in. You might go to gym also, but maybe he goes to gym 4 days/ for 2hr at a time, but you go 2days/hr. The point is that people don't know the difference in definition between Casual and Hardcore. Hardcore is someone going all out, putting everything into it, whether its more time, energy, focus. Casual players just don't prioritize the activity over some other activity.
If you watch the day of a casual player and a hardcore player, you would definitely see the difference, even if they both have same responsibilities outside of the game. I was a hardcore gamer when I was younger. Why? I loved playing videogames. I could play for hours, put insane amounts of time into playing, learning everything about it. I also was a hardcore Basketball player. That changed when I got married and had kids. I played basketball casually. couldn't work on honing my skills when I had other responsibilites. I was still a hardcore gamer, but that diminished as those years went on because now, instead of me playing maybe....50-100hrs/week, I was getting in about 15-20. Casual means time spent doing said activity, doesn't mean lazy or unskilled.
Casual reader vs. Hardcore Reader: Is the casual reader lazy? Does the hardcore reader read with such ferocity they burn holes into the pages and is the master or words? Casual reader could be an english teacher and the hardcore reader could just be consuming comic books.
Casual baker vs Hardcore baker: Would you assume casual baker is inept and can't even tell the difference between salt and sugar? Would you assume a hardcore baker can make a cake out of 2 twinkies, a pound of butter, and determination? Casual baker could be a professional chef that enjoys baking every once in a while and the hardcore baker could be a grocery store baker that bakes premade bread and cookies by the buttload.
So boys and girls, Casual vs Hardcore is about time spent and priorities, not skill or motivation.
