A small but nice detail regarding Ian: his sprites change to have more visible muscles and some characters take note of his improved physique if his fitness reaches certain threshold.The male MC is 5'9 or 175cm it's an average height. He is like a blank slate, you get to mould him as a character. Sure if we get steroid use later in the game he can become like Jack. You can make him much better than Eric from the previous game.
