Sims 4 is the best selling base game of the franchise.

Thing is IMO these days EA sees Maxis like EA Sports, a division where they can extract the maximum of profit for the absolute minimum of investment, but better as there are no franchises involved who get shirty when things get long in the tooth. And it won't change when for every person who complains about lack of features and bug on the forums, YouTube, reddit and Twitter there are 20 who will buy everything on release day. And the Game Changers program is still structured to make the game changers (many of who are young and impressionable themselves) think they are obliged to be unpaid publicists for EA (despite their claims to have revised it), which is despicable.
