The game will still be playable, but you will have to make a number of victims. Existing players will have to download Photo 4 – The Sims 4: Previous Edition /, A frozen version while using the old standards. It will only work with plug-ins on packages released in February 2019 or earlier, and online features like gallery, game banners and social-tie ins will stop functioning. You will also not get bug fixes. It's not that subtle to push and update your PC – the EA is just making sure you do not stay completely if you can not justify upgrading right away.
