Tutorials... Oh yes...
Well, I'll agree with Atomic Gazelle on a cutscene tutorial. I believe that should help many people out.
Also, the dialogue tree can be extended by letting the show choices command having the possibility of scrolling through multiple messages. So like
Message; Can I have your phone number?
Show choices[Yes, No, Whatever, Ñext]
1.
Yes
2.
No
3.
Whatever
4. ~Next
Show choices; [I'm going to report you for stalking, don't have a phone, *kill*, ~previous]
EDIT; Ah sorry ccoa, I completely forgot about yours (probably because I've never taken the time to actually read through all that)
