Sure,people would love to see Sims 4 go on to 2025 and beyond,but let's be realistic here: the Sims 4 engine is starting to show its age....look at how many bugs and glitches keep piling on now. The game engine might last until sometime in 2021 or early 2022,then the game engine will break.
And even IF the game engine managed to run until 2025,how many people would still be playing Sims 4 by then? How many people would of switched to Paralives or some other life sim because they got fed up with more years of shallow gameplay and constant bugs and glitches?
Sims 4 has been around for 6 years now,and I see more and more people going back to Sims 3, Sims 2 and even Sims 1. Why? Because Sims 1-3 has more gameplay and the Sims have much more personality. Those games have a LOT of content and a LOT of different things to do. Sims 4 has shallow Sims with no personalities and there's hardly anything interesting to do. We just keep getting the same old boring gyms,boring libraries and boring bars plunked into every new pack that comes out.
It's time to move on. Let Sims 4 end in late 2021 or early 2022and let EA put out Sims 5. I have a feeling that Sims 5 is going to be 100 times better than Sims 4.
