4 definitely lost its soul after it stopped being a Maxis game and became an "EA" game.
However I'm going to go out on a limb and say that even 3 partially lost its soul. For many people it's considered the "best" Sims game, largely in part due to the open world and how everything became so much more fantastical and silly. Less a life sim and more "My vampire ghost hunting tomb raiding super Sim who knows kung fu and can time travel into the future!" Just too much dumb shit. Don't get me wrong though as I do think 3 is a fantastic game still, it just doesn't feel like the first game or even second.
2 partly headed that way for sure but was a nice middle-ground between 1 and 3, yet still closer to 1's vision.
