They did get two things right, the multitasking and graphics are wondrous.. maybe I just love the Sims 2 too much that I can't deal with change lol. Sims 4 is probably one of those games you have to get used to.
I have little experience with Sims 1 and Sims 2 but I think that the earlier Sims have a certain charm to them that you cant carry on to the next games. Maybe its the nostalgia you get from playing them, idk. After playing Sims 4 you see a lot of glitchy stuff in Sims 3 while the gameplay in Sims 4 is much smoother. Haha. I can't describe properly for the life of meee.
