hello everybody!

I have recently gotten flash making software and have taken a lot of time learning it. I deffinatly am not good at it what so ever and i was hoping that someone could help me. I played a few rpg games that i found particularly interesting. They were mostly games in which i was given background information about the main character and then it gave me a couple options. I could click on whichever one i wanted and then the game would say what my character did and what happened next. Naturally, i was given some more options. The game would go on in this manner and the story line would be shaped differently based on your choices and such. I liked these games more than your average rpg because the entertainment came from mostly the story as opposed to poor combat and lvling systems. If any1 can tell me what these types of rpg's are called id really apreciate it. Also, if you could, can you give a link to a video that shows how to make these games (cause there rly hard to find).
Thanks.
