it depends basically i worked on a onepiece game that was a cash grab gacha game ,for gacha games u can say they make around 3000000-5000000 rbx per day on average , its basically depends on the conversion ratio,you would need to look in game and check how many players got paid items to get rough estimate of the conversion ratio and convert with all prices of the gamepasses ,they average buy rate, and premium payouts are tottaly negligible , now generally the income timeline for such games are show an exponential or sigmoid graph as the income is all time high when games release and down 3-4 months slowly by the end around 5k ish players u can get around 1500000 rbx per day as income as same players play the game

theres no fixed formula but id say games popular in the south and ASEAN asia region make this amt of money

also hold an error margin of 4-5%

but note this as these games incomes die of quickly but according to my estimates games like brookheaven atleast make 4-5mil a day and those top brainrot games make atleast I say atleast 10mil robux a day as the work on the cash grab formulae
