Just being sarcastic and I'm not a pleasant guy. Anyway, forgot the number but quick google says percentage of f2p that ends up spending cash are between 0.19% to 2.2%, lets round it up up to eleven, yeah 11% of 2000 is 220 persons, and lets be generously-generous-as-a-generous-god when assuming each of them spend $100 monthly, thats $22k monthly revenue, their other game titstitan of fapmonkey or whatever will probably have revenue akin to winrar.
Aand to avoid derailing from the topic I will say: gacha rate sucks, my advice for them is at least try to provide entertainment instead of being a wannabe underworld gambling den. They nerfed the overall gacha, by now its too obvious to ignore, just search youtube for peoples rolls in nutaku's kamihime, afterwards ask yourself, does that look like 3% to you? like 4 out of 5 vids are having a lot less SSR than what they're suppose to be getting. Like people only able to liquidate 60% of estimated gain, like the rates is actually in reality is 2%!!
