The Sims team has provided some additional details on Origin Access Premier, Origin’s new PC membership tier announced at EA Play. If you purchase/upgrade your membership to Origin Access Premier, you will be automatically upgraded to The Sims 4 Premier Edition.
This version of the game will grant you access to The Sims 4 Dine Out Game Pack, and The Sims 4 Kids Room Stuff Pack. If you don’t already own these games, playing saves without an active membership will affect your saves going forward. If you already own the addons being offered in this membership tier, then this would not affect your game.
Maxis also reiterates that this membership tier will allow players to access new games prior to their release, but we do not yet know if this is being extended to The Sims 4.
With Origin Access Premier, you get unlimited access to The Sims 4 Deluxe Edition, The Sims 4 Dine Out, and The Sims 4 Kids Room Stuff. You’ll also get over 100 other great PC titles to play as much as you want, and you’ll get new games before they release. No trial, no waiting.
If you own The Sims 4, upgrading to The Sims 4 Premier edition may affect your save files. Going forward, your saved games will only work with versions of The Sims 4 that have access to the same Packs that are available in The Sims 4 Premier edition. If your Access Premier membership expires, you may need to purchase additional Packs to load any of your new or updated game saves.
