If you choose to be vegetarian/vegan then in food scenes alterations pop up to mention that the options are vegetarian/vegan versions of the foods rather than the meat/animal product versions (as in, it's not cow milk you're picking but instead the "milk" is soy or nut based or what have you). If you didn't see that than that'd be a bug. But you're right that this is just a game where it's up to you to make choices. If someone wants to name their MC "fake-name3" or something silly, they can. We wouldn't wanna take away the option to decide your own name because some players might choose to do something weird with that decision. Same for choices. You can use the options that are there to make a defined, consistent character or you can use the wide range of options to make an MC who behaves in wildly inconsistent ways. That has to be left up to players to decide, otherwise the game becomes far more restrictive.
