This would get you some extra money through the C-store. If you level up a character to Captain or so and then realize you would rather have another species, there is no way to go about doing that. Would you consider a species-changing token in the C-store?
At least a few of the missions involve using holo projectors for disguises so your idea could appear in that form if there's enough practical interest to do so. Small c-store purchase for holo disguise item.
Not very 'canon' for permanent change in character species however...
I like this idea / request. I choose an Andorian when I started (thinking I could later change) only to realize that I couldn't. I did post a similar request in another thread (I forget which one now) but yeah... It would be nice if they allowed us either to create a second captain (for the same account) or to edit our species along with our attire and appearance.
Q: Captain_Kell: With the addition of new races in the future; Android, Hologram, etc. will there be a way to change the race of one of our established captains?
Dstahl: The “change species” feature has been discussed for some time and we currently do not have plans to add this in the near-term. However, we recognize that some players want this feature and so I wouldn’t be surprised to see it in game eventually. There is a lot of tech between here and there on the back end to make this work the way we want it to.
That said.. I would very much like to see this functionality added to STO.
Q: Starfish1 Are there any plans to give us the option to re-trait our characters?
A: We continue to discuss this internally. It does require some changes to how we have the characters setup on the backend. If we do add this sort of feature, it may be a pay service similar to how WOW and other MMOs change your character. Your character may also be offline for a short amount of time while we alter it. The big thing is that many of your costumes and character features are very specific to your species, so once the conversion takes place, your character might look pretty messed up or not capable of looking how you wanted. That is the biggest hurdle we have to tackle before we can offer this.
One way they could deal with this would be clear out all saved uniforms/outfits and force the player to save a new look on the character in the tailor (as the new species) before the transaction would complete and use the species change token up, or keep the character's progress/level, XP, etc. but require the player to select new traits (and the aforementioned new appearance) before letting them play on the character.
