Yes, the creation section can be quite large. At times when making the game, you may find that another part might be needed to the character, then the creation section would need to change. I am working with 2 groups, 1 has the creation section added, the other has not yet started on it. In the one with that section already in, I find I am needing to make changes several times adding new things and removing old. This section might be best done after the other sections are in.
If you still want to work on the creation section, there are many possibilities of setting it up, as there are many diff types of games. Basically, its a menu with a series of sections, where each section works on a different part of the character. They can be just a menu system, or the character can also be there. Choosing classes from a list, starting stats, abilities, spells, skills, any number of different parts that the character might need. There is a also a tutorial for changing the cloths on the base Hero Engine default character. Its a good idea to get your Game's character in as the same functions might not work on your character.
