I don't mind the sims we knew and loved from Sim1 - Sims 3 not being the same in Sims 4. It's an alternate reality where the previous canon doesn't exist as we all know it. To me, New lore to match an alternate reality doesn't bother me as much as the feeling I have to have minimal mods and probably too much CC to make the game worth playing for hours at a time. It doesn't bother me as much with every update while playing vanilla the game has serious issues and is broken with lots of last exceptions and them needing to scramble to attempt to fix everything that broke all because EA thought hey let's update and not play/beta test this game properly. Leaving it to modders to fix everything that ends up breaking.
However, I think I see where you are coming from hoping that Sims 4 would have continued and improved where Sims 3 left off.
