The information is in there it shows both halves of the game made about 60 million pounds each in the years 2020 and 2021 though revenue is trending towards OSRS. Like I said you can look up their in game population right now, RuneScape doesn’t hide population numbers, log on and the numbers are right there, for example right now OSRS is at 120k and RS3 is at 15k
DT came out right at the end of Q2, the playerbase didn’t fall that fast and you are comparing it to a year that don’t the entire time in a drought. Q4’s numbers are unfavourable compared to the equivalent quarter after EW (though we don’t have Q1 for this year). I never said it dropped specifically by 75% but I do agree with the wider point that the population is not trending in a healthy direction
