This looks like it's going to be a big update. Given the history of updates in the Sims 4, I can't wait to see what kind of creative bugs and glitches come with it. With that in mind, I have to wonder how this level of new features, potential customization of Sims, and the tons of new information that have to be processed and rendered will impact the system requirements for The Sims 4. The newest expansion pack comes out before this update is even released, and new expansions put more stress on computer resources. The recommended system requirements for The Sims 4 don't seem adequate to me, unless you're only running base game. Couple that with the amount of CC and mods that Simmers bring to their game, and it seems that the game will require a more robust system than what many Simmers may have at their disposal.
I'm no expert, but I haven't seen this topic addressed when it concerns a major update like this.
