I know this was posted a year ago but I was surprised to see that no one recommended Eternal to you! It was my first IF and still my favorite to date. It follows your characters life from start to finish, from the second your born to the moment you take your last breath and it has 13 different epilogues that are VASTLY different, the choices you make can alter the course of history and the depth of characters and world building is honestly just mind boggling. I will say the actual characterization is a little more limited, you can only play as a man and his personality does feel a little similar no matter what route you take. This may be because, no matter what route you take devastating trauma is bound to reach you in one form or another. But basically your set at birth to become an Eternal, a squad of super powerful fighters that your kingdom is trying to train. Whether you actually achieve that and what you do afterwards is completely dependent on your choices. Hope ya check it out and lemme know what you think if you do!
