Patch 1.70 is not a content update. It contains no bug fixes, new features, or Store fixes.

Q: Does Patch 1.70 work with all expansions? A: Yes. It works with every EP and SP, including Into the Future and Sweet Treats.

Q: Will Patch 1.70 delete my saved games? A: No. Saves are stored in your Documents folder. However, it is wise to back them up before any major patch.

Q: My game says 1.69 instead of 1.70. Is that okay? A: Yes. Patch 1.69 was the Origin-only update. Patch 1.70 replaced it for EA App/Steam. Functionally, they are identical. The Sims 3 Patch 1.70 Download

Q: Does the Smooth Patch (by LazyDuchess) work with 1.70? A: Yes, but you need the version specifically compiled for 1.70. Version 2.0 and above works flawlessly.
