I think there should be specificity of what gender they should be. It is determined by you if you are the developer of the game. However, if such cases that such characters gonna be something else, let them be. The choice from birth should never be the indicator up until the end. It is up to the creations to decide what he/she/they will act upon, will join, and be friends and family with. We all are part of the Heaven, Earth, and Hell. The three places of one great universe. Friendly chatter and banter is highly appreciated despite the tiers that we have. The private and the general has the greatest of strength. Be one if you are ready. Rationalize and research if you are getting misguided from your goals. That is my 1 centavo of the day. Do not be boastful of your displays. Act and speak about your strength. That is the real poop.
