Story progression would be nice...if we had some real, in-depth options in addition to more "broad strokes" options for everything from marriage to population growth to which sims the game is and is not allowed to progress (on both a large and small scale) on its own. I like how MCCC gives us so many options for that sort of thing and I'd love to see it applied officially in the game. After all, the in-game options (population, aging, house filling) are pretty skimpy. Some meatier options would really help bring some additional depth to TS4 for more experienced players while also giving newer players something to tinker with from save to save to keep their experience fresh in each playthrough. A rising tide lifts all boats, and all that jazz.
