The Sims 4.5 - What would you like to see? (Interview with Graham)

I would not call the possibilities with the sims4 "humongous". The same game that was released in 2013 is still there and the way Maxis are making packs have not changed that much.

A sims 4.5 would take so many more years to make that when we have reached that point, fans are not even going to feel that it is a 4.5 because too much time has passed.

Upgrading the game is not going to happen.
