I had a lot of fun with TS1 but I skipped TS2. I tried TSO (EA-Land) for a couple of months until the sunset and I could see why this is one of Will Wright's most ambitious work. In 2009, I was still converting skins and decor items from TSO for TS1 when TS3 was launched. Finally found my way to TS3 in 2010.
Two years later I begun to try Store stuff and they are not so bad. Only after TS4 problems I can really see TS3 with a new perspective, appreciating the whole works that ultimately made this technically much more professional than TS4.
So after 2 years, I still don't care about TS4, they've missed the momentum and all they do is vaguely saying that they still work for something.
