I passed by this game aeveral tomes thinking I had already played it and lost interest. I ran out of things to play so I decided to give it "another try" and I definitely have never played it before. Great game and great story, only wish I had gone longer before discovering it so I had more to play. What is the difference between 4.6 and 4.5? I just downloaded the other day but mine says version 4.5 and the D/L here says 4.6.
