true, true. But there was a consent rule. An example would be someone coming in to play a Vultaran, the cruel, extremelt volcanic race. Having players in the same race heightens the risk to the race, and also can throw off the general idea of the race. :/
I'll have to think about it, but keep in mind, the Chozo are a peaceful race, though scientific and very military. They aren't afraid to get their hands dirty as they haul out the big guns. And, due to being in a new galaxy, their security is pretty high, along with the recent attack by the Holis, of which they are finalizing their defenses. So, due to security, the rules are strict at the moment, meaning a lack of free movement for military ships. But, overall in the racial mentality is the sense of logic and military disapline from their war-like past. (That's not to say everyone is born a soldier, just that they are all trained in self defense)
Chozo:
Peaceful (never starting a fight with another race unless in self defense or to aid allies)
Logical (like vulcans, but mildly open-minded)
Scientists (war)
Engineering (war)
Strong military background (war)
Adept in engineering and science, as well as the ways of war
(photon beam cannons, lasers (gattling gun has been seen in use), missiles, Cracker bombs and various other explosives, strong shields and good engines on capital ships, drone fighter/bomber/scout hybrid. (technologies developed mostly for... war)
Strong mining fleets, harvesting the nebulas, and asteroid/planets (gas mining fleet, and mineral fleet. Solar Mining station gives the fuel containers to freighters)
Nova Shield (designed to withstand the supernovas, as the sacrifice of power, and possible minor damage if not aligned correctly. Drains power from all systems and takes a few minutes to do so. A complete flush of power leads to surges and heavy damage from supernova. Crew will survive)
Jump Gate, 1 way gate unless connected to eachother.
Other technologies under developement: usually spur of the moment by the Chozo to adapt to new situations.
If you do play Chozo, I think it may be hard to keep them in character to the racial standards. Single character standards is no problem, but if in amilitary position, military policies apply.

(they also respect the scientists, and engineers as that's how they get the guns and tech they want

)
I could lay it out in greater detail if you want, but this is just a brief destription
