I wonder why Matt missed out the information about why they did it, as it is pretty relevant
Developer did it with a little glitch hidden inside the game - people who download the pirated version play the game alright until the very moment where a player gets a message that the first video game their company will start selling will be pirated - thus making the company bankrupted and losing the game, forcing to start over.
Actually I didn't mention everything to keep the suspense. :p
Btw, the glitch was not when they created first game, but when they were on level 7-8, so it annoyed the hell out of gamers.

And message was something like you make game, and it people pirate it like hell. "Sir, too many people pirated our game and we are going bankcorrupt.
What's even funnier is people asking online, OMG WHY DO PEOPLE PIRATE?!! (when they pirated the game themselves) oh the irony. lmao
