First, may I say well done to Cryptic on getting them in here finally (I've only been back ingame a couple weeks and did my first one last night). All those Diplomatic Investigations were actually worth suffering through to get here.
Second, I'm still somewhat scratching my head, since it did end up feeling very....shallow. The one I had gave me a trio of moral challenges to opening relations with the new race, but it felt after the final interview, that I could have said whatever I wanted and it wouldn't have mattered to the outcome unless I just flat out picked the one idiotically obvious bad choice in the conversation tree.
Any chance these might someday lead to tailored follow up contact missions?
You can just pick anything...although that will only net you 10 diplomatic xp. If you choose the answers that correspond to the conversations you had, or to their trivia about the Federation, it nets you an additional 10 for a total of 20 diplomatic xp for the mission.
I would like to see a feature added such that when a player correctly answeres all of the questions, a random green quality Alien BOFF with the same look as the species you just interacted with offers to join the crew. It would encoruage the players to pay more attention to the dialoge, and players who are fans, and already know the answers would be rewarded.
