Ah, that old topic. My two cents:
When I look at my bookshelf I see dozens of boxes of computer games there (e.g. all CIV games / clones). I need not feel bad for software companies - they quite obviously got a fait share of my money. And I enjoy an original game with a nice, printed manuel and the occassional goodie (The ULTIMA series always excelled in this, having maps printed on cloth or other specials in "hardware").
Having said that, I have downloaded "pirated" versions of games quite often. In fact, I got such a version of CIV4 before I got the original game. Why? Because it was available before a demo and because it allowed me an uncrippled test of the game. Ok, admittedly, with CIV i was pretty sure I would want the "real thing" anyway, never mind my criticism on the graphics and several details.
However, I have had my share of original games which, after 1 or 2 games, turned out to be crap and a waste of money, totally independent of what the box said or what "reviews" told me. In fact, some years ago, buying a game for me was a game of chance, with roughly 15% being good games, 25% being "ok" and 60% being "I wouldn't have paid the money had I known what I get for it".
I'm a quite demanding customer when it comes to games, but if a game company manages to earn my respect, it earns my loyalty, too.
I am lucky that CIV runs on my desktop machine (choppiness and all, but it runs). If it had NOT run, i wouldn't have bought it - I would have deleted my "pirated" copy and that would have been it. So talk about "piracy" as an insurance against badly programmed software I cannot run properly anyway. I see not the slightest reason to have a bad conscience here. ABSOLUTELY not.
Ah, and one more thing: Comparing software "piracy" with theft is rubbish, of yourse. You don't steal anything - you COPY. That is, there is no DIRECT damage to anyone, because nothing is taken away anywhere. Those who know a bit about law know that exactly this is what makes handling of "piracy" so difficult. It is no "theft" and it can't ever be - so you end up with copyright infringement and the like, things that are seen as lesser crimes compared to crimes like real theft.
This does NOT say that piracy in general (especially when it REPLACES you buying original games) is ok. It's just that one has to acknowledge 3 simple facts:
a) There is no "theft" element involved. Media companies of course try to sell it as "thievery", fully knowing they make it up. Repeat: "Piracy" IS NO THEFT.
b) To an extent, "piracy" is the answer to lies of the companies. They lie about what a game would do, lie about on what machines it runs etc. So the answer is to lie about how you legally got the game - until you have proof that their claims hold true. If they do, this is the moment when you are morally required to pay. Fair deal: They keep their promises and so do you. Two sides of a contract. (IMHO, of course. Maybe you do not agree here, but then, you may not have such a collection of bad games like I do. I do not intend to enlarge it.)
c) We all know the argument how big the losses of companies are because of piracy. Come on, we all know that this is a lie, too. People who DO download "pirated" copies would never, ever BUY the same amount. They wouldn't. That simple. Quite a lot actually are "collectors" who enjoy to have big software collections they quite often COULDN'T buy even if they wanted. There ARE losses, of course, but they are much less than what the companies say they are. As if each illegal download would replace one bought original. Ha-ha-ha. I don't really feel like discussing on such a poor intellectual level
So, to sum it up: I actually LIKE buying games. I LIKE to have a good feeling about it, having printed manuals, a nice box and such (hey, I even like the SMELL of a freshly opened game!). What I HATE are false promises, software that doesn't run on my machine and those &%(O)($ copy protection mechanisms that force me to fiddle around with a disc. In fact, my original copy of CIV sits on the shelf nicely just know - I run the "pirated" copy (I *do* have a license, remember?) all the time. Go figure.
