I have a Sim in the Detective career track right now. Have been going to work with him everyday. I'm a massive, massive fan of detective games (Especially point and click detective games!) and so I was super excited about it.
I love all the interactions, especially the interrogation bit which is a bit like a conversation puzzle- you have to chose the right actions to make progress.
I'm not happy that each crime scene seems to be vandalism. Maybe it's because Joey is only level 3 and not even a Detective yet, but I was kind of hoping for at least a little variety. I'm also not happy that when you get the witness report it's just something that goes into your inventory. Aside from viewing the crime scene, which tells you the nature of the crime, and then finding clues about the perp, you don't get any information. You just kind of repeat the same actions over and over. Fingerprint, Go on Patrol, Check Database. Wash, rinse, repeat.
My sim has been taking some pictures. I was a bit saddened to see the Mysterious Mr. Gnome pop up in his failed shots, because if I remember correctly it was literally the same picture from the Sims 3 and it felt a bit lazy to me. I loved what happened when my Sim asked his girlfriend to pose for him. I do a lot of the Sim & Modeling stuff on the officials and I just thought when she turned her back and posed it really was striking.
So far we've only taken small photos, but having them makes me happy. While I do love simatography, family play and legacies are my Sims bread and butter and I like being able to have photos that span generations. I took a picture of my Sim's girlfriend pregnant and playing piano and it was like she was playing to the baby, too sweet!
Speaking of the pregnancy, she had the baby at the Hospital and I got to go with her. That was pretty awesome until the Doctor removed her heart and almost killed her. Y'know, small mistake. I was disappointed that the boyfriend idled himself over to the nearest computer to Play Sims Forever instead of choosing to be in the room with his soon-to-be wife as she gave birth.
Can you have twins at the Hospital? I truly thought my Sim was going to have twins. Her belly was massive, but at the Hospital- just the one. I hope that the Hospital doesn't force a single child situation, I'd really like to make my Sims have their babies there.
No aliens in my game yet. My male is too overworked trying to top the Detective branch and my female Sim has been caring for her child and trying to fulfill her aspiration. I really, really want aliens, but I also want to explore the Scientist and Doctor careers so aliens might be a bit further down the line.
Oh! When my Sim reached level three of the Detective career, he got quite a few items as bonuses including stuff to make a prison cell. Thought it was amusing that the Police just hand that out, especially since other sims could be heard saying things like "Did you just get your badge yesterday?" and "At least you managed to put your uniform on right side out.."
(A slight note about what may be a weird NPC thing. My male Sim's girlfriend was the town Librarian, and when she moved in she was missing a trait. Nothing that bothers me, and I'm not even sure it's a Get to Work thing, but if it is I thought I'd note it.)
