No game can possibly achieve absolute fairness.
Rich or poor, talented or untalented, people gain disproportionate rewards even when they put in the same amount of effort.
A long time ago, in the era of mouse and keyboard games, people competed on the agility of their hands. Some were born with more agile hands, like adept pianists whose nimbleness overshadowed that of ordinary players.
Of course, this is just a metaphor; those talented in piano are unlikely to switch to gaming.
However, one breed of gamer did possess faster hand speeds: single male homebodies, the mainstream in gaming then. As long as they had enough... nutrition... cough cough.
