I'm still play my TS3 game so I get my CASt fix. B)
As for TS4, I miss it horribly. It's not even for want of patterns (though I would love to be able to add my own) but for more basic color options. While the pre-sets are nice and some do have a variety of colors on certain objects/items, they can be severely limited on others. The fact that many shoes in CAS don't come in basic black is mind boggling to me. Another example, cribs. I wanted to do a nursery in red and white but when I went to place the bassinet the only color choices were pink, blue, yellow and green. A plain, white bassinet, a neutral color that would have gone with everything, was simply not an option. Like I said before, mind-boggling.
If EA decided to nix CASt, then they should have taken steps to make sure that the color options they did offer would be more dynamic. And since the game is proving more difficult to mod than anticipated (despite EA's claims to the contrary), it may be a while yet before Buy/Build CC and recolors start to roll out to fill the void.
