The Sims™ 4, life to date, has almost 36 million players

if these numbers are true, I can see why EA would want to continue developing content for the long term. Sims 4 is the most accessible Sims game ever, it's on 4 major consoles, runs relatively well on modest PC's and Macs, and is available on a few subscription services. Launching a new Sims game would sabotage the huge platform Sims 4 has. Why launch a new sims game to sell DLC content to a new and growing player base, when you can continue selling DLC to an already existing player base?
