I would just like to say this because I have seen some of the stupidest reason regarding being able to play or not play the out planets (Gas giants) I would like to get the record straight and say that [b]THE GAS GIANTS WILL [u]NOT[/u] BE PLAYABLE SPACE[/b]. The planets will not be playable, but the [b][u]MOONS MANY [/u][/b] be. This means that the Traveler may have Tara formed the moons and they may be playable. It embarrasses me that I need the clarify this... But I have been reading the posts from these kids trying to prove people wrong by saying"there's a surface under the clouds and you can walk on it!" There is a core, but the pressure is so -blam!-ing unfathomablely strong, that it's not even worth talking about. But before you say "Helljumper, what about the Traveler's space magic!" No amount of space magic could fix that. The only exception to the gas giants would be a structure similar to the thing(I forgot the name) from the 3rd or 4th Halo 2 mission. Please bump this so as many people can see this! And if you have any other theories about it, I'm all ears... Edit 1: to all of the people talking about the moon... All you would need to do is add mass. And if need be move further away from earth
