No. As others have said, pirating games is not the best way to go about insuring future titles.
Edit: Just about everyone downloads stuff. As much as I hate to admit it, I've dled much, much more than my fair share of music. I've cut way back, and buy virtually everything now. However, people who say dling software, music, applications, whatever is NOT stealing are clearly confused or something.
Copying a game or music tracks for yourself is the same thing as walking into a retail store and pocketing CDs. One can argue that it's not as serious for various reasons, but it doesen't change the fact that you own something that does not belong to you because you did not pay for it.

Person 2: Wait! It's amazing! Unique, charming, drop dead gorgeous... Hello?
