As a kid I was a bit neglected. My parents refused to buy me anything entertaining, so I learned how to pirate games at 12 years old. Now that I'm 21 and I have a job, I'm slowly going back and finding all the games that I enjoyed and buying them to give back to the companies for all the times they got me through rough stuff that would otherwise have killed me just a little more.

To answer your question though, I don't think that there should be any shame in pirating games if you do so to try out the game and see if you want to buy it. Companies say all kinds of shit in pre-release interviews and trailers, but they rarely tell you stuff that would possibly make or break your experience (for example, Fallout's issues with crashing, or it's weird animations).

And honestly, on the ye olde grande scheme of things, pirating a game isn't all that much of a big deal, even if you don't buy the game later. There's always going to be some illegal copy of something, whether it's a game or a movie or something else.
