I love Sims 3. It is one of my favorite games. Although I take breaks from it (read "I get addicted to another game for a time") I always come back to it or balance playing it with several different games.
For the past several weeks my current addiction is Conan Exiles that I play on line with other family members and friends where we have formed a clan so we are collectively helping each there and building several "bases" as we explore the world.
Another game I play often is a strategy game, Civ IV (although it has newer versions, I like IV).
To replace Sims 3 and never play it again would take another similar game (sims or not) with improved graphics and improved gameplay (Sims 4 has neither of those) but having all the best of the Sims 3 including an open world sandbox with many ways to be creative.
