Newsun: I like it.... like really like it, but I wouldnt get to carried away if (and or when) they engage in combat. They own the ocean no doubt, but in space its pretty much an even playing field. Other then that, its accepted I like the direction its going in. Pick a place on the map.
Shadow: Im going to need you to downsize, the resources required to sustain your population would be immense, not to mention the space and planets. Also give me some more details with your racial traits, telepathic psychics can be what the Zargonians have ( which is good) or mind reading and mind destruction ( Which is OP and not good). Other then that just finish it and it will be good.
