I guess I don't disagree. Clocked a lot of hours on Sims 1 and Sims 2, so did my wife. I didn't know it was still popular though. We kinda stopped caring, and most the people around me did as well. It is hard for me to gauge appeal these days, since a game series could start to suck like a toothless whore and still get a dozen more sequels. I give Sims credit for really turning the key on game expansions leading the way to DLC. On that list, I feel most of those games were smartly chosen because they were the source game for a genre or major shift in gaming, so I see the point of the Sims being on there.
I still would put my hat in the ring for SimCity, especially when considering that most freemium games out there are very much cloning SimCity in some capacity.
