EA has announced a rewards program that will unlock special bonus digital content in The Sims 4 for anyone who owns and registers their copy of The Sims 3 and any of its expansion packs.

A total of 13 rewards are available. The Sims 3 base game and each of its expansions (World Adventures, Ambitions, Pets, Showtime, etc.) each come with a special lamp serves as a memory for your pervious adventures. For example, the Late Night expansion rewards you with the "UV Light Award," designed for Sims "who love the night life, and who maybe miss seeing this thing called the sun." If you own and register The Sims 3 and all 11 of its expansion packs, you'll be rewarded with "The Ultimate Freezer Bunny Award," a trophy in The Sims 4 "so large, your sims will barely reach its shimmering pinnacle."

According to EA, each reward "will affect your Sims' emotions and personalities in a unique way."

If you previously purchased your games on Origin or if your game already appears in your "My Games" library on Origin, then it's already registered. If not, you can find instructions on how to do so here. EA notes that your rewards will be waiting for you in your Build Mode catalog when The Sims 4 launches in September 2014. The Rewards program will end on December 31, 2015.
