BerserkLeon said:Let's be generous and say for DS it was more like 25%, since it was dead-simple to grab a flashcart and go. Maybe 5% of the total userbase knew of Cing, so I'd guess 5% or less of the pirates knew of them. And I imagine maybe 1/3 of that 5% of that 25% were responsible pirates and bought the games after discovering they liked it.
I am not sure your model works -- raw numbers might be one thing but demographics and such like count for a lot more (drop all the homophobic 12 year olds from COD and you will see a bigger player number drop than if you dropped all the grandmothers, despite being represented about as well in the population at large).
As for the subject of the OP we have done this basically every month since forever.
