In 2014 EA Games offered The Sims 2 Ultimate Collection for free download via Origin for a limited time of one week. Only people who grabbed the free download at right time can re-download the game at any time. Sadly, I missed the moment.
Some people uploaded Ultimate Collection on various file hosting services, where anyone can download for FREE: https://mega.nz/#F!tT5GkB5Y!8tEL-uoB7_aJG8Il9CREyQ
However, the Ultimate Collection, although contains the full game including all expansions and stuff packs, it do not contains expansion packs individually so they cannot be played with AnyGameStarter, used by me to create basegame-compatible content.
You may have been aware of BitTorrent filesharing network, where you can download games for free. But The Sims game is split on multiple torrents due to having numerous expansion packs, which require entering serial numbers which may take a while to find them and install all expansion packs, whole job taking about 3 hours.
I found one torrent which automatically install all expansion packs, you are no longer needed to install expansions one by one and enter serial numbers:

How to download torrents (if you are not familiar)
You need to install a torrent client, such as uTorrent or Vuze. Then go in the above link to ThePirateBay website, click Get this torrent, it will open with the torrent software you installed and start downloading. When the download is complete, open Sims 2 AIO Installer.exe and the whole game including all expansion packs will install in about 15 minutes. After this you can install AnyGameStarter if you want to play base game only or specific expansion packs. If you want to play via AnyGameStarter you need also to add cracked EXE files for the expansion packs you are playing, you can download The Sims 2 Crack Pack. The base game should not be cracked because it prevents Build mode from working, you need to play with disk in drive or in Daemon Tools.
You can browse ThePirateBay website for other games, software or music for free download.
You can find serial numbers by searching “The Sims key” on Yahoo Answers.
Is legal to download from torrents?
Simply using torrents is not a crime. But free downloading games and software that are usually sold for money, stealing serial codes or using cracked exe files, is a crime. However as long you are using them only at home, non-commercial use, is no problem.
For example: discotheques are regularly inspected if they own (paid for) the music they are playing, internet cafes are regularly inspected if they own (paid for) games offered for playing, but if you are downloading music and games from torrents just to play at home without making money from it, there is unlikely for a law enforcement authority to ever inspect you.
Your place of living also matter. Authorities in Eastern Europe, Asia, Africa and Latin America tolerate piracy more than in North America or Western Europe.
