To add to this when doing research regarding subs I found -
"In a new analyst note, Mike Hickey from Janco Partners has been examining Blizzard’s World Of Warcraft success in light of the Activision/Blizzard merger, suggesting average monthly WoW revenue in “the low teens” per user, and a churn rate as low as 4-5% per month.
So now let’s go back and look at that graph with an understanding that 5% of the population leaves every month. For ease, let’s just look at WoW West, which includes the US and European subs. It remains steady at around 5.125 million from 2009-2010. Assuming a 5% churn rate, that means 256,250 new subs had to be gained every month (on average) just to keep steady.
Now, let’s look at… well, any other year. 2005-2006, when the WoW phenomenon took off? WoW went from 500k to 2.5 million subs in the West, meaning that it had to maintain the 500k it already had and gain a total of 2 million more. 500k * 0.05 + 2m / 12 = 191,667 subs per month. In other words, vanilla gained new subs at a 25% slower rate that year than Wrath.
The next year (2006-2007) was 2.5m * 0.05 + 1m / 12 = 208,334. Again, almost 20% less.
It is not until the 2007-2008 release of TBC that we see Wrath being overtaken: 3.5m * 0.05 + 1m / 12 = 258,334. The difference there is… 2,084, or 0.8%. Basically a rounding error. The last year of TBC is a bit sketchy depending on how you want to interpret that final tick on the graph. If it’s 4.9 million, then TBC gained the same 2,084 number more. If it’s any less, Wrath wins.
If you want to follow the global population line instead, the figures come out as follows:
- 2005-2006 = +537,500
- 2006-2007 = +477,084
- 2007-2008 = +562,500
- 2008-2009 = +625,000
- 2009-2010 = +575,000 (<—Wrath)"
So even with a churn rate of 5% the time that RDF was in the game gained more subs than Vanilla did.
