That's great logic. Let's consider a car, which you can get checked out by a mechanic/friend/somebody for problems. If you know or pay someone who is savvy with cars to look it over, it saves you a major headache and money down the line. If you don't, and buy it site unseen without driving it or testing it, that is your problem.
Let's consider a videogame. You can read reviews, watch videos, and sometimes even play a demo when it releases. If you don't do any of that and buy it off of what the cover looks like, that is your problem.
However, if I buy a game that is nothing but buggy, cannot run on my computer due to a software conflict that was not mentioned somewhere, does not work with my hardware (we'll patch it down the line, 2 months later), has continuous server issues, etc. etc...that is not your problem. That is a problem on the developer's end.
What you apparently fail to understand is that nobody is walking into a store and robbing someone of a physical copy of a game. They are simply downloading a file off of the internet. That is in no way stealing, and certainly does not equal a substantial reduction in profits, because half of these people aren't going to buy the game anyways. Not only that, but after some people, like myself, get to try a game, we end up buying it regardless.
Then there comes the part that games that have things like Ubisoft always on DRM cannot be played while offline (granted I know they are working on this/not using it/removing it or something I read), so a crack is your only option to enjoy the game like you want to.
A car is physical property, an .rar of a game is not. It's pretty damn stupid to think that they are anywhere near the same thing.
