Just because somebody thinks a game is overpriced, doesn't mean they have to be in the industry or even know anything about video games. People see different value in different things. Personally, I think the fact that 3100 out of 3314 players chose to pirate the game shows how possibly overpriced people seem to think it is.
Kudos to the developers for the prank though.
You can put the best of best game out there and charge players only 10$ and you will get the same results. To most people free is always better
Especially when it is so easy
