Its not just you for sure. Sims 3 felt like an adventure to me. There was always something new to do and something new to discover. I still go back and play my Sims 3 and typically find some little thing that I never found before (or just don't remember having found) Sims 4 has some wonderful features, but as far as pure, unadulterated content, Sims 3 always felt like a bigger world from base game on up through the expansions and stuff.
That said, I'm excited for university and hopeful that it adds in some of the great content I long for.
