I thought it was a great demo anyway - gives you enough to see how the game plays and how you can pick different choices - it shows you that you can only select so many of the choices before the game advances - so if you pick 6 of the 10 offered to you the next time you play you can try the others you didn't select. Nothing huge will differ in that scene but say for example you don't help someone you'd have to assume that will come back to bite you on the ass...and if you do help them then something different will happen later.
