Well, honestly, if the activity HAS to be team-based, without it you would get almost zero merit because you couldn't even do the task in the first place!

Counter: Merit is subjective and usually argued to another person, like an interviewer.

But some say within nihilistic views, there is no "real" merit! As it's subjective.

Though merit needs an observer - the observer would be able to see the teamwork!

And lastly, it depends on how much society values the task. Exams are probably valued more than videogames. That is it.
