Yarp. I need mods.
EA story progression is kinda trash, so I use MCCC. Without mods, Sims don't reproduce and my worlds stagnate and die off. I also use Slice of Life to add a little spice to my game. Sims become more lifelike with it. I'm always open to considering other mods to add. I tried Wonderful Whims (NOT the dirty one), but couldn't get it to work right. Loved the attraction system, but it was causing my already paired off couples to break up, which was messing with my stories. :P
