I'm quite ashamed that you guys would pirate an indie game that costs £8.80, I didn't expect that on here of all places. He is only one guy so you can't even use the "big faceless corporation" excuse which is rubbish anyway, you think it's the executives that suffer from loss of sales due to piracy? If sales drop they just cut staff to cover their own salary.
This is such an innovative and charming game, I have no money yet I still paid for it, you can't justify stealing because you don't have money, it's not like you need Minecraft to survive. I would feel guilty every time I played.
Notch has made a lot of money out of this already but this is no excuse, he is setting up a business now which he has to pay for, employees and lawyers he has to pay and I am sure he will put most of the money back into developing his business, expanding Minecraft and making more amazing games. It all costs money and if you're pirating Minecraft you are preventing that from happening.
This could be a great games company in the future, and seeing as there are dozens of threads complaining about the "profit before entertainment" philosophy of big companies like EA, I'd have thought you would all be supporting and encouraging this fledgling company, not stealing sales from it which it has rightly earned.
