dBLOOD: Thank god I save all my GoG games on an external HDD! I wont let them take away the games I have paid for!
They are not taking anything away.
If you already own the original game and buy the Enhanced Edition, you get the Enhanced Edition added to your account and still keep the original. You will then have both versions of the game.
If you don't own the original and buy the Enhanced Edition, you get both the original and Enhanced Edition added to your account. You will then have both versions of the game.
What some are upset about is that if you already owned the original version of Baldur's Gate, Icewind Dale or Baldur's Gate 2 when you bought the Enhanced Edition, then you received a gift code for ANOTHER copy of the original, essentially giving you two copies of the original version. That didn't happen with Torment. You don't get a gift code for the original, you just get the original added to your account if you don't already have it.
