I agree with other posters in this thread who have said they think it is EA themselves who are changing the whole style of the Sims game which may be possibly attracting a different fan base. That's great for the new Sims 4 players but not quite so great for all those long term players who have loved previous games and remained loyal for a very long time as a result; long term players who would have preferred their enjoyment of the game to continue into Sims 4. If it ain't broke, don't fix it! These are my sentiments too. Why change something that was clearly working exceptionally well with a huge number of followers? Yes, ADD to it for improvements but don't TAKE AWAY what was so good about the Sims.
The most noticeable thing lacking for me personally in Sims 4 is that I cannot manifest onto my screen whatever is in my own imagination; something I could do in Sims 3. (Sims 3 did have some limitations but nothing like the limitations found in Sims 4) I can't create the personality I want in my sims - the sim will behave exactly the same as all other sims no matter what traits I give it. My sim will still fart in public or waddle to the loo no matter how prim and proper I make them. My sim will still sit with strangers when going out on a date even if my imagination conjured up a very close couple who would spend every minute together. If I add a grandma to my game, she will still burn the breakfast simply because she is new to my game. How many grandma's burn a breakfast? It doesn't sit well with me.
Why can't I match up rooms, doors, windows, wood, etc? Why can't I create an environment that I can see in my own imagination, as I could in Sims 3, like change the town, change the world, change the environment? In Sims 3 my criminal sims looked and acted like criminal sims; not so in Sims 4. It's the little things that made Sims 3 better - my sims could pop across the road to a neighbor, or drive (walk, cycle) to town. They could wait outside the police station for their partner to come out of work; they could wait for the children to come out of school, they could run across fields or down to the beach and visit the graveyard at night to see a ghost. They could sell their home produced stuff from the consignment store. They could go and make out backstage at the theatre or the town hall, pop across to the park and sit and eat with a friend, visit the bistro, drive to the beach .....so many things they could do. I could create a farming area north of town, take my sims on a cookery course or a handiness course. I could build a small cottage or caravan park up by the waterfall that my sims could visit. My imagination had almost free rein in Sims 3. Now in Sims 4 I find myself following a list of things to do, a checklist ......do this, now do that, now this......... I don't want to be reminded that the children are missing school when it was part of my plan for them to miss school. I want my sims to be able to walk into the hospital whenever I want them to, not have to take employment there in order to do so.
Anyway, I had better stop now because I'm moaning about the game again and it's making me feel negative. Why do I bother? I stopped playing long ago when it became absolutely clear to me that this game was never going to be the same; that this game was never going to offer me the brilliance of Sims 3.
What I really wish the most is that instead of taking away what made the Sims game so good, was that they would ADD to its brilliance with an updated version. It's clear that is never going to happen and that is why EA have lost my custom. Oh well........ :(
