Yeap, indie, mobile games seem to be a 1:10 legitirate ratio, if what I remember from articles from World of Goo and Game Dev Tycoon, vs. 5:1 as according to this report's.maninahat said:And that's only considering mainstream games; aren't indie companies getting the worst piracy ratios?
But as I pointed out with their monitoring for only 3 months, I think the number could be much higher - as you're looking at FO:NV's 5 million legit copies over, what, ~2.5years? To 1 million pirate copies over 3 months. One would have to figure out the drop off rate and project it to estimate the ratio for the game's life to date. The charts from the report suggests it drops off by 50% after a month, but I don't know how that projects to later months (since we know there's always going to be someone, somewhere, downloading).
And they're only monitoring BT traffic, what about newsgroups, IRC, filesharing sites, unscrupulous stores selling the pirated copies? Granted those numbers are probably much smaller than BT, but it still adds up. Or trackers in foreign countries that they're unaware of? I remember reading an article how Company of Heroes had 800k unique patch downloads from China, yet Relic had not released the game there at all.
While I agree publishers grossly exaggerate the numbers, I also think it's still higher than this report suggests.
