The reason I state all this can be idt that Jagex are gunna start pouring all their resources into OSRS gold and firing out updates every week. It is not broken at the moment, and it's a fragile thing. The'future of Jagex' is not attempting to speed up the process we are seeing for the two games, it's about keeping the momentum moving without breaking it. It's clearly functioning as is at the moment.
You will notice that if they contribute a few to each match (43M RS3, 65M OSRS), which adds up to 108M, but the actual revenue throughout 2019 was 110.8M. Maybe part or all that unaccounted for 2.8M is unredeemed bonds.
You are not adding additional income, product at 2.6m and advertising revenue at 225k. Add them to the RS3 OSRS amounts and it is logical.
In addition to this branchout, the two years had 3 DXP events but 2019 had one extended over a 10 day period. It's quite interesting that the huge boom in OSRS inhabitants did little to stop the decline of MTX revenue; I'm inclined to believe that 2019 was way, way worse for Cheap Runescape gold's MTX than the stats (and the document) state .
OSRS is obviously doing gangbusters. No real surprise there, the game's been doing incredibly well and everyone knows it.
I'd recommend getting wary, though; I recall a couple of months ago there were rumors the bigwigs were starting to look to OSRS since the future due to the financials, and this sort of data would actually encourage that talk.
