Given the context, it did seem like trolling. After all, the question appeared to be posed within the context of the plot and the ME universe. Not the real-world, which rules out "because then the game wouldn't happen" as an answer. Now add the facetious nature of the rest of the comment (disparaging the plot as "retarded" and characterizing it as a five minute revival) and it's pretty obvious why it appeared to be trolling.
