I didn't buy here in GOG, I have in Steam and EA/Origin, let me put in a very simple way, it's a game you play, replay and play again and after sometime you come back to play more always differently! I've been a human, dwarf, female elf, noble, low caste, urban slave, slave abolishonist. Whatever the game has to offer you, it always changes dialogs, unless you try hard to always get the same results I found myself even following the same choices with different results. It's a must!
