We all know a "true sims fan" in EAs point of view is the one who will keep throwing them money http://www.picgifs.com/smileys/smileys-and-emoticons/money/smileys-money-702364.gif.I believe we all fit into that category.Any individual who continued or continues to spend money after buying the base game is a fan.
As to the leaked photos for TS4,I'm just not feeling it yet.I'm not a builder or creator of any kind and although I use CC my sims are not really fabulous.I'm going to have to see and hear what the actually game play offers.I'm a plop and play type of player so actual things to do and places to see is where they will have to wow me.When they announced TS3 and told us of the opened neighborhood where our sims could get out and really explore their world,and where our neighbors would age along with our sims,that is where they sold me.It will have to be something great that doesn't include online game play.
DM-just grabbed and recommended your finished world.
