As a student who basically lives off the scraps of the economy although piracy is certainly wrong, I would be way less educated now than if I didn't endorse in such an activity. I study in media, observing what makes TV, DVDs and games tick (or not tick). Before you go out on your 'YOU'RE A THIEF!' rants please read on carefully.
Because my money is limited:
Simplest of reasons really, I don't have the money to buy both the modern media and classic media, and buying a game that is pure crap is not much of an investment. I have to place priorities on what I buy, and with the average game being somewhere between £30 - £40 that doesn't leave a lot of shuffle room.
I was skeptical of Yahtzee's almost too good to be true review of Saints Row 2, so I pirated it first. Going through my mind as it downloaded painfully slow were things such as 'GTA clone, probably about some bland gang and a pile of money'. A mere 3 days after playing, I bought the game on Steam, and listen to everything Yahtzee says.
What I'm trying to say with this is that piracy is a kind of like a testing ground; ensuring that I know what I would be paying for, and asking myself 'would I actually buy it?'. There's little to go by for games, with demos lessening in number and only a trailer to attempt to read between its lines. Is it morally wrong? I can say yes, but there were times where I'd have never paid for a game if I didn't see what it really was first.
Because they don't sell Touhou stuff here
I love ZUN's Touhou franchise, it is perhaps my biggest guilty pleasure. The brilliant bullet patterns and some rather excellent fighting games although with some arch-typical and a little blandish characters is something I really would pay for, so why am I not paying for it?
Because its so far away, importing costs a lot, and I really can't afford that right now, especially with the amount that I've bought off of Steam recently. This isn't even counting all of that fan content that I'd also feel like paying for, but again, costs a lot and its purely for guilty pleasure as a weaboo rather than to engage in deep analysis.
But I'm not a theif! Well, not entirely...
However, even with these reasons, I've made effort to buy games and media. I'm a victim of the Steam sales, Steam's digital distribution is so much easier than pirating (not having to worry about seeders, so much quicker d/l speed with my slow connection) and feels flawless. Theres the question of online multiplayer that I do want, and theres also my conscience telling that I'd want to contribute to the developer who made something that entertained me.
There are always going to be the people who will pirate purely because its free, probably the people who pay the most for internet connections and terabyte hard drives and less on the media industry, maximising the effective use of their money.
This is purely my perspective: slow internet, skepticism and foreign software. Theres also the fact that I definitely can't afford the software that I have to learn to use (Photoshop and Maya). It is morally wrong, these ARE excuses, and I'd love to be able to pay for everything but I have to prioritise my purchases in order to educate myself better about media. I hope this perspective has opened some minds and educated some on this sensitive topic. I also suggest you google
Stephen Fry, who has opined his well educated thoughts on the subject of piracy.
