The great Geneforge Saga! Developed by Spiderweb Software ~ They make many great games in which you choose your own path, who you want to side with, betray him? Excellent game developed by an in credible dev. team. Bringing the depth of "Old-School" RPG's back to the present day, they are doing a great thing. I recommend supporting them by purchasing their other games if you like the style of Geneforge (their other titles are a more traditional setting and mechanics, they are excellent)

I will add the winner to steam. Thank you! :D
