I too had about 10 original games and over a hundred cracked ones. Back then I didn't feel guilty about it at all. Games were very expensive, and also there were never too many original games on the shelves when I was a kid, even when the Amiga was booming. So I used to copy games off my friend - save money, and get access to heaps more games too.
Times have changed alittle bit. When people say that "piracy killed the Amiga," I feel abit guilty. As for modern PC software, I find it way too expensive. Let me illustrate:
New release book: $30 (Australian dollars)
New release CD: $25 - $30
New release DVD: $30
New release PC game: $100 or more
What the hell! I just can't bring myself to pay that much for a game, especially when you can complete many of them very quickly these days, and also because 95% of modern games are complete crap. I even refuse to pay that much for an iD Software release, and I am an iD junkie.
However, if I do really, really, really like a game which I have burnt, I wait until the price has come down abit (to say around $30 - can take a few years or a few months), then I buy it. I do feel abit guilty burning software, becase I am a creative person, and I know how hard those guys who make games must work. So I don't want to freeload entirely.
But, I feel antivirus software and antispyware software should be free. All of it. It shits me that people are making money from people's net and PC insecurities and fears.
