You could have just said that you wanted a DVD copy. You could have easily ordered one from Larian studios without a fuss. Instead you do this.
While it is a good idea to have physical, non-internet copies of games, many will cause a loss of features and updates this way.
Furthermore, once you have purchased a game, be it from steam, a publisher, or store shelves, there are multiple ways to keep it safe. You could install it on a portable hard drive for example.
In addition, I feel it is perfectly okay to make copies of games so long as it is within the context of the law. Pirating games is obviously illegal, doubly so if you do so for financial or other gain. You can, however, legally make a copy of a game such as D: OS provided you have paid for it or acquired permissions (either one), you do not distribute the copy(s) for any reason without the publishers and other parties express written consent, and finally, it must be for personal use only. For example, you could buy a game online and download it. Copy it to a disk or portable hard drive, and take it so you can install and play somewhere you do not have internet access.
However, Pirating the game just because you don't want it off of steam or some such is stupid and a crime. Plus telling the world publicly that you pirated a game...on the developer's OWN FORUM SITE!! Hello?
Oh and by the way, you can bet that Larian studios will be reporting you to the authorities if the FBI doesn't nab you first.
