What year do you think will be The Sims 4 last year before its no longer being developed for? Sims 1 2000-2003 Sims 2 2004-2008 Sims 3 2009-2013 Sims 4 2014-20??
2020 makes a lot of sense, but personally I'm hoping for 2019 so a new, hopefully better, sims game is being worked on sooner. But maybe sims 4 will surprise me while it lasts
