If you don't want to consider the fact that SF may ruin your drive, consider some other aspect, like the intrusive behaviour. When I installed SH3, I meant to only install that, but then I discover that it has also installed a hidden system driver, of which they've never said anything neither in the box nor the manual. It's like a virus. You download some data, but you also get some software of which you don't get any notice, and may damage your system. Before buying SH3, I only knew that SF existed by reading the forums, but I didn't knew what it was, and if it really was going to be implemented. If I didn't have Internet, I may have never noticed that I had a new system driver installed.
And I don't say that companies shouldn't protect their property, but that they should use some other methods like they have used before. Anyways, it's a waste of money, because every game is already cracked after 1 or 2 weeks of being published (this is real, no invention, nor any try to promote the use of warez & Co.)
Cheers
