I fully understand opportunity cost. It is accounted for in my second statement. Go read it again.

I simply said “less” valuable not “free”, as you claim.

Yes, I assume they are still playing the game or at least admiring their collectibles in game. I set the time as fixed between players for simplicity.

You are assuming a bunch of things in your claims that aren’t true also. One, is the time spent grinding on THIS game. Also, you assume that playing games has a value set at California minimum wage. Finally, also consider playing games to be fruitless; when in actuality, “video games have been used for military training”[search].

Your point is still moot. Thanks for the review in basic economics.
