Definitely adventure, especially real-life experience and sci-fi

Choose Your Own Adventure? That was waaaay awesome when I started back then

From there on, I've moved to Lone Wolf and all sorts of stats-playability game book

--> http://en.wikipedia.org/wiki/Lone_Wolf_(gamebooks)

It's a role-playing gamebook.

Think of it like Choose Your Own Adventure + game statistics (lifebar, magic bar, number of arrows, thickness of your armor, etc).

On any pages where you meet an opponent, you have to defeat the opponent in order to move on to the following page.

A simple example:
- Lets say your life now is 20, his life is 10. You start first
- You roll a dice, and if you hit 6, that means you hit him and deduct his life by 6 points (so that now his life is left as 4).
- Next is the opponent's turn; you roll the dice again and this time you get 5, which means he hits you and it deducted your life till 15 now.

So this continues on until either you win, or you lose.
If you win, with your remaining life, you continue to the following pages and on with your adventure.
If you lose, you start back from the start
