Each race has advantages and disadvantages. Some have more powers then others, but the other race might be stronger or wiser then the other. Each race depends on what you like best. It is best to go with what you know or what you enjoy. If your a good and holy person maybe you should be a cetra. If you like the space and stars, maybe you should be a starjin. If you like bare fighting maybe a human or saiya-jin. It is all your decision.
You may also create a race and play the character from it. All you have to do is send me the race name, biography of race, forms, advantages and disadvantages. Do not worry you do not have to do this immediately.
