You were either given a starter creature, or you assembled your own, and that is when everything went into motion. Your very own creature was brought into being.
Your creature is a virtual person. It has a virtual body, and virtual feelings, virtual strengths, and virtual weaknesses. Other than that, your creature is whatever you want it to be. Your wish is its command.
When you first start out, your creature will be totally dependent on your care. During this, you are learning too, you develop alongside your creature. You make skills to make your creature's life easier, and in return, it does whatever you want it to do. You teach it to take care of itself, and if you are successful, you get points, so you can make an even better creature next time.
You are the driving force within your creature. You decide what its hopes and dreams will be. You decide what makes its mouth water. You decide what it likes to do for fun. You have total control, and because of this, there are many systems put in place to help you get the most out of your experience. If your creature feels even the slightest discomfort, it will show up on your scanners in some way. Hunger, thirst, pain, sadness, tiredness, fear, and other problems will show up.
Your creature does not immediately act the way you want it to. It changes and adapts to your treatment. If you make it eat a poisonous plant, it will get sick, but if you keep feeding it poisonous plants, it will build up an immunity to it. Not only that, but the strengths and adaptations that your creature develops will be passed on to its offspring. Your creature may really hate water, but if you force it to swim, it will adapt, and it will start enjoying the water. Your creature may naturally be a weakling, but if you make it a body builder, it will become strong, and it will enjoy lifting weights. Your creature may have a tendency to not think things through, but if you force it to stalk its prey or read or do math problems, it will learn to be patient and intelligent.
As you know, your creature is a living virtual being. This means that it can learn and forget. It can become stronger and weaker. It can get better at a skill, and it can get worse at a skill. Simply making the ultimate skill for your creature to perform would be too easy. With each new skill, your creature has to learn the moves, and slowly improve the technique. For instance, if you create a skill of using a hammer, your creature may not be very good at it, and miss a few times, maybe even hitting its thumb, or whatever passes as a thumb. Although it takes practice to learn skills, the muscles that your creature uses most will adapt more quickly than less-used muscles. This means that if you make one skill very similar to another skill, it will be easier to learn.
When your job is done, and your creature has died (or mated), it may be only the beginning. First beings, or creatures which you have directly genetically altered, have dominant traits, so they can mate with similar species and produce offspring exactly like them. Otherwise, when you create a totally unique first being, the program creates temporary mates for it when it is mature. Either way, you may find descendants of your creature, roaming around where you left it, doing things you taught it to do.
A Haunting
When the end comes, you may choose to stay behind and admire your
creation. When your creature dies, you can leave its body and haunt the
general area until you log out. As a ghost, you have several abilities.
You can make the wind blow, or make spooky noises to scare other
creatures. What you will probably use it for most is to wait to be
revived, or to possess other creatures (of the same species only).
