You need to think more out of box.
And dont take this too seriously.
Typical capitalistic gamer is 16 years old kid.
His mother have limited his computer playing for 4
hours. Those he decide to invest to RO2 (which is
bad choose, COD would be better
when thinking profit)
By investing 4 hours of his life he gets certain amount
of spawns. Those he tries to spend best possible way to
get as much points as possible (By being on every possible
cap, when its capped and then leaving it, so that enemy
cap it back and it can be recapped once again).
By getting allkind of points he earns medals.
And on the end of the day he can show his fancy medals
to his friends, and get adoration from his friends = profit
If he doesnt have any, he can also post screenshots
about his points to some forums.
