I agree I don't think it's a good decision to keep The Sims 4 going forever and I strongly urge EA to reconsider and start working on a sequel. I have been with The Sims 4 since the beginning and you can feel that EA/Maxis wants to do a lot with the sims 4 packs but they can't because of limitations. In so many cases they resort to rabbit holes and notifications in the upper right.
We the players are constantly reaching limits on what we want to do as well, we can't redesign worlds, we can only replace lots and the sims themselves. And these limitations comes into play with new packs as well, many reacted when they saw the new sims survey about pack ideas that a lot of them sounded like what we had before, or could be because of all the limitations. A water ocean world sounds great, but if diving is going to be rabbit holes and not much else then it's going to be just like Island Living.
The players and Maxis are going to be creatively bankrupt. And when people want to be able to do more, is The Sims 4 going to be able to handle that? Didn't Lyndsay Pearson say that they are never gonna be able to do something like Newcrest or Windenburg again? Because those worlds are too large.
Also, don't you want your community to grow? Don't you think you risk reaching a limit by not developing and improving? I understand you want to go for the mobile market, and by all means, do that with Rene, but don't leave the PC/IOS market in the dust with The Sims 4.
And hey, I'm not saying to stop making sims4 content, a sequel will take at least 5 years to make, and isn't that what Laura Miele said? They wanted to keep the sims4 going for 15 years?
