The game is not worth the $8 and is a rip-off of a Japanese game with almost the same name.
How is this a good example?
People pirated it as a demo, does not mean they HAVE TO buy it. Playing a demo does not force you to spend money on a game..
Your logic is flawed.
Like year and a half ago I pirated PZ, played it an hour, bought it. Worth it.
I do not like watching Let's Plays, because it removes the interactive moment of it. Demo's are OK.
