My reason is because I'm cheap. 'Nuff said. For you see, I simply don't have the money that developers think their products are worth. Microsoft Windows ME launched for $499 AUD. Hmmmm, I had the choice of spending 50 cents on a blank CD and getting it, or blowing $499. My copy of Microsoft's last work of art, Win 98 had decided it didn't want to work anymore.
That's not to say I feel bad, I do, slightly. Although I'd feel much worse if I actually spent $499 on what was basically a bloody beta test (I swear, ME's first release was the buggiest application I've ever had the pleasure of using)
I however, will never go as far as getting a pirated copy of a game (Excluding ROMS. Tell me Nintendo, where could I buy a copy of Secret of Mana 2 with the added English translation? Thanks) or a DVD. Hell, even my VCD's are official. For one, my PC is much to crap to run anything, and two, I enjoy official stuff on PS2/Whatever. Game developers offer me hours of fun, and I pay for that fun. Easy.
And music... Well.....
If I really like a band, I'll buy their album. But as time marches on and on, I'm finding it harder to like mainstream music. My tastes lay in obscure unheard of bands splashed all over kazaa and 8/16-Bit video game music. When was the last time you saw a soundtrack to the likes of Stunt Race FX in the shops? Yep. Never.
Do you really think if people stop getting free software, developers will lower the cost?
We see advertising all over movies, does that make the movie cheaper to see/buy? NO.
We see advertising splashed in game manuals, IN games... Does that make it cheaper? NO.
Their saving does not pass along to the consumer.
