Random chance is something you may want to stay away from. Especially if like me, you are just learning this stuff. You can do it, certainly, but it can cause continuity problems between scenes or some random errors if done wrong.
For myself, I am very much a visual learner and it has helped me a great deal to use a choicescript SDE. Basically a program that helps you write the game/code.
There are two out right now on the forums.
Chronicler is the one I am using currently. It has allowed me to build a game very rapidly.
The other is CSIDE.
I have not really tried it but some people love it!
