In just about every form of science fiction the inevitable cross-species happens. Yet how likely are these romances to work out? Shows like Star Trek would have us believe that the majority of the alien races out there can crossbreed between species, resulting in a half and half. While universes like Mass Effect shows us that do to differences in biology crossbreeding between species is generally impossible, save for one unique exception when it comes to the Asari.
My question is does the idea of whether or not children are possible decide if a particular inter-species relationship is acceptable?
Would you consider such a thing?
What about the difference in physical appearance? Using the Universe of Mass Effect as a example of extremely different physical appearances. You have the option of romancing a Turian partner or a Drell one if you control a female shepard. Do you think you could commit to a relationship where your spouse was a member of one of those two races?
