Jack Emmert, chief creative officer of Cryptic Studios, was interviewed by the Associated Press about Cryptic's plans for Star Trek Online:
"You'll venture through space exploring new civilizations and life-forms," said Emmert. "You'll also beam down to planets and have adventures inside your ship. It's a galactic-wide game. There's going to be tons of space to investigate. We have a great system for exploration, which will allow for almost infinite possibilities."
So can we name our new species that we create? What if other players want to make one as well for RP reasons, will there be a template of some sort?
Well, considering all star trek aliens (with a very few exceptions) are basically humans with various different bumps and spots on their head/hands, I imagine there will be a ton of variations and if two happen to be very similar (romulans/vulcans) then its no big deal, you just explain it away with "oh the race was split when one faction took off to found their own dealio" just like they do in the show.
