It's still a really good series, but I really didn't like how there was only one ending. I'd prefer it if you just picked one and went from there, like you did this time ;P
Thus, instead of the 5 you usually get, you had a lot of points knocked off for what is an ESSENTIAL part of Choose Your Own Adventure games. The whole -point- of these games is for your choices to make a difference. When they don't affect the outcome, the game becomes pointless.
