History does not record piracy figures.
Good to see it do 1m but is has been in the bargain bin for a while, I know because I was looking to get it for someone (but afterwards thought it might be a bit too "grown up"for them). Back then a brand new copy at Amazon was for less than £10.00.
Selling it at such a low price (and I don't think it was that long after release) isn't good for the developers and from what I have seen of it, they deserved a decent financial reward for their work.
I hope at the very least the developers broke even.
