It really does work! I ended up contacting EA a few weeks ago because I lost the code to my original sims 2 game (I was feeling nostalgic), I asked for a new code, and even though I missed the offer for UC they still gave me a whole new sims game after asking for my Origin ID and email, they put the game in My Games on Origin, I checked what it was expecting it to be the base game of TS2 and it said 'The Sims 2 Ultimate Collection' I was stunned and so happy! I didn't even ask for TS2:UC and they gave it to me. It's honestly worth a try to ask for it if you don't have it :)
