For me, Sims 3 was an absolute trainwreck. I tried to adapt. I really tried. But, the game play didn't fit my style. Now, Sims 2. There was a game. For my playing style, Sims 2 was about as perfect as it could get, and I would be playing it today instead of Sims 4 if it weren't for the improved CAS features. I loved everything about Sims 2. For me, even the base game was satifsying, although, of course, I loved the expansions and felt that each added important features to the game. Comparing base game 2 with base game 4 is difficult, really. Overall, I think my vote would go to Sims 2. Sims 4 is enjoyable, but as someone else mentioned, there are too many features missing. I'm not talking about things that came along later. I'm talking about features that should be part of the normal "life simulation" based around a life cycle spanning birth to death. I still find it incomprehensible that toddlers were omitted. That was my favorite stage. And, where are the cemeteries? I suppose we just simulate life until Grimmie shows up and then toss our dead sims into the garbage? I don't care for the career choices in Sims 4, and I'm still old-fashioned enough to want newspapers delivered to my door. I want clothing stores (I think Cold Issue was included in the Sims 2 base game, wasn't it?) I loved taking my Sims shopping, especially when they were shopping for a wedding. I'm all about realism in my simming. I feel Sims 2 had a far more realistic approach than Sims 4, so that's my main disappointment right now -- despite all the pre-release hype about it.
