Everyone covered most important issues but one many consider important (not everyone) is it uses the deadly startforce protection.
So if you are intent on trying it I suggest installing it on a secondary master drive or secondary computer to avoid any serious potiental problems.
I didn't have any serious potential problems.
Furthermore, Larian did in extrem cases give the player a key, if they wrote to them.
But I don't know to which distributions this applies at all. I recently learned that only certain distributions in some countries can get this key.
But what's even better : If you *really* want the game without the copy protecten, then go and buy the German "Gold Games" compilation ! The version of :BD: in it doesn't have the Starforce protection at all !
The worst thing that sucked was the distribution by Ubi Soft : After the game was sold out, they simply didn't manufacture any more copies.
You cannot believe how many people asked in the German part of the Larian forums for that game !
