Just a PSA that Planescape Torment Enhanced edition is now available for PC or for Android or iPAD. I personally went with the Android version and it plays great on my tablet. Best $10 I ever spent.
If you don't know about Torment, its probably one of the best (I personally think it's the best) RPG ever. Great story and it's really about choice. The party members are also the most diverse and most interesting of any game I have played.
It's old school and definitely a lot of reading involved. But give it a shot.
