Sims 3 player numbers

I do not have any problems with sims 3. Have not had any lag in a long time. I believe it is what world you are playing in. Now in Sunlit Tide I had some lag, due to the fact that a dog kept getting stuck in one of the parks, as soon as I fixed it so they could not get stuck anymore, it quit the lag. I do not have any cc or mods, and most of the time if it lags, I start looking in the world for someone or pet stuck and can quickly fix it so there is no more lag. either remake the lot or delete it and replace it with another one. Once I fix the lot, I save the world as a rename, so I do not have to do it again. My computer plays very well with sims 3 and 4, but I do not play much with 4, I have tired to like it, but just can't get through even one generation. I am not sure what it is. Well one thing I cannot delete the school and I do not send my kids to school, takes up to much of their time and cannot play with them much, and I still can't seem to get my head around the teens as they seem like college kids. to prove that. In sims 3 a teen cannot live alone, unless the adult dies. now in sims 4 a teen can live alone and that is because they are college age or going from 10 yrs old to 18 so that is why they can live alone. I do like sims 3 the best. I have been trying my best to like sims 4, but it is just not happening, another thing is that in sims 4 it seem that EA wants you to play their way, hard to change things your own way, like the monster under the bed things, even with the light sometimes the kids can't sleep. I better not go on, it is not nice to keep talking bad about a game, as some do like it. ;) As far as sims 3 I love it.
