Well Dynasties = bloodline and natural pregnancies. It's not that the team is making any kind of social statement on gays because we're not.
I understand how it is, Metro. When you commit to the Immortal Dynasty, or any Dynasty(hint hint: Please put up another Dynasty challenge soon! The Life States Dynasty was my favorite challenge in TS3, but I know you can't do it now because we haven't gotten any expansions yet so please let us know when the next challenge is coming!
), you must make compromises or sacrifice things that you like to follow the rules - I would love to have a wedding park in Oasis Springs, but I can't do that because rules say that the home lot is the only lot you can have a wedding arch in because editing other lots is banned.
Gay marriages are fine early on because you have room but once you hit Generation 5, you have to limit additions which will add more immortals(aka true weddings and pregnancies) and once you hit Gen 7, if you have a boy, you have to give them a sex change so they can get pregnant outside of wedlock, and Gen 8 can't have any babies at all! I can see why some Immortal Dynasties have the final Immortal become gay, because if they can't be pregnant anyways, the closest romance you'll have is a boyfriend or girlfriend.
But when the challenge ends, you'll sit back and take a snapshot of all eight of your old-as-dirt immortals sitting in a line before their house, smiling because "You're done, congrats." And if you're going for HoF(I never do because I can never get over using testingcheats to keep needs up
) you'll get your picture in the Hall of Fame and join the ranks of the Elite. So, as one Youtuber would say, "We're playing for high stakes - risky business for risky rewards."
