I think it is you who needs to familiarize yourself with that term. Cash cow means a steady flow of income for as little maintenance as possible. that is not what oasis have.

Oasis have a tiny bubble of spenders, there is little competition there and what oasis have done in their infinite wisdom is make that bubble even smaller by hiring most of the top whales, effectively stripping some of their only paying customers of their need and motivation to spend as they can increase their power just from using the coupons oasis pays them to do literally nothing whatsoever.

It could be, and should be a cash cow, but only focusing on a tiny number of players,only having them spend in small windows and then pro actively taking away your biggest spenders desire to spend and ignoring a huge chunk of the player base that would spend if this game did not hike prices up so ludicrously high that we would need to win the lottery to pay for the hobby, that is not a cash cow and the solution is so obvious the fact that no one in oasis can see it means they are so * it physically hurts me to think about it.

If they had a range of events, some tailored for the rich, some tailored for moderate spenders and some tailored to keep free players around and game traffic high, then it would be a cash cow, then they would have a steady flow of income instead of bursts of high spending from the 0.01% followed by periods of no activity. Also this would mean slightly less "work" for them as they would still just be copying creations from chinese developers but by simply not adding so many zeroes onto literally every single thing we get in comparison to other region prices they would open the game to a whole demographic they are currently ignoring for no good reason, just an unfounded level of st3pidity.

The average recharge price would drop, true, but the number of recharges aswell as the frequency would significantly increase and as I said it is slightly less "work" for these paid chimps and boom, there you have it, one actual cash cow. Steady income/huge profit margin/minimal to no work/happy and active consumers
