Hmm, no, in this case no argument is better than the stupidity you’ve proven capable of by comparing unofficial pirated downloads from one single source and not even taking sales numbers or any of the other 4 billion factors that influence sales of a video game into account.
Let me destroy your brain real quick: people pirate and then buy the game because it was good or it ran properly on their machine or they liked the gameplay. Surprise surprise!
Oh wow, your anecdotic evidence taken out of the ass, without any stat how many people actually do it to back it up, so it means nothing, really blown up my brain, good job. :)
