It is kind of funny, I played both games. Dragon Age I enjoyed more in the end, as I always loved classic RPGs, even with all the dialogue. At some points the dialogue did get overly heavy (Orzammar, spent three hours just in the damn city talking to people), but I felt it really let it tell a story rather then just have fight, after fight, after fight.
Sims 3 I enjoyed a ton also, but when something happened that actually annoyed me so much I have yet to go back. I made an amazing house by a river in one of the towns, worked as as a journalist, and finally decided I wanted to get a wife for my little avatar. Met some woman as a protest in front of town hall, she was married already, but I stole her away! muahahahaha, then we got married and I found out she was 5 days away from becoming an elder, and I was still a brand new adult. I was so disappointed by that I actually stopped playing, I was going to be unable to do the things with the character I wanted to do.
