Better than the alternative!
Manual based DRM was always pretty good, though it could be gotten around. Things like the Starflight2 and SSI D&D games made it harder. Still, no system in the world will ever be 100% secure.
I am suprised at one thing though. In many states (and perhaps in other countries) - you are legally entitled to a backup copy of any software you purchase / license. Usually the License Agreement prohibits this, but clauses it with the fact that your locale may not allow that prohibition and that you may have other rights under local laws. However, DRM makes such copies - when in the possession of the original purchaser and legal under the law, still be non-functional. I am curious as to the legality of that - since if your original media is damaged the publisher usually charges you for a "copy" from them. One could make the arguement that, because the original purchaser is entitled to a backup copy, that copy should be functional - as otherwise its of no use. If a publisher has a legal requirement to make such a copy functional - well that would be opening up a can of worms....
Something to think about.
Anyone know much about this subject? My knowledge is limited on it at the moment.
