The newest iteration of the franchise is The Sims 4, which was initially released in 2013. Instead of maintaining the same gameplay year-after-year, there are so many changes that take place.
The key to this game being so successful is the constant reinvention process that it has undergone. Since initially debuting in 2000, The Sims franchise has continued to grow over the years, and with numerous expansion packs and versions, the game is still going strong almost twenty years later.
