I definitly think that the races should behave like who they are supposed to be. I mean, whats the point in having Star Trek races that behave nothing like what they are supposed to? It would be like just changing the images of existing races so that they would look like star trek.
The second option is really the only option. I want sneaky, backstabbing romulans, agressive but honorable klingons, greeeedy ferengi, etc.
Just my 2 cents.
