Option 1 is more intriguing to me from the dark plot and LIs' interesting...ness. Different species are really welcome~
That said, if option 2 has NSFW *wink wink* content with that eggs and mate plot, I'd pick it hands down. Though from your description it seems pretty safe. Of course, I understand not every developer is comfortable with creating nsfw stuff, please don't take my opinion too seriously.
Enjoy your vacation! Let your mind and body relax during that time!
