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??
I was going to vote 2020 but idk...I feel like there's room for more expansion packs (if they stick to the yearly schedule). This is just a random guess, but I personally hope Sims 4 will carry past 2020
