Dunno if there are any rules here, but fitgirl repacks a lot of games and thankfully The Sims 4 is one of them. She's repacked the full game + all the expansion packs up until strangerville (which I think is the latest EP).
Again, dunno about the rules but here's a direct link to fitgirl's The Sims 4 repack page:
The Sims 4: Deluxe Edition – v1.50.67.1020 + All DLCs & Add-ons | FitGirl Repacks
Use torrent or download from one of the links on the page, whichever suits you.
Let me know if you need any other help with it!
