Honestly I felt it was pretty on par for an RPG game. Many quests have multiple outcomes, you get follow-up quests depending on how you handle certain things. You have about 3-4 separate endings to the game.
Most games don't have the kind of choices people actually expect and still get called rpgs. Skyrim for example has only a handful of quests with different outcomes and it's still considered a great RPG, although I myself have severe criticisms of it.
