This would not only be super fun, but also very practical. There are some simmers who like the eternal sunshine and rainbows, thus they may not want darkness. However, if it is in a pack, they don't have to buy it and their games are nice while those who want edge can get it :)
I miss drama in the sims. TS3 was so amusing and fun when my sims and other sims started figthing and then formed all-out rivalries without me doing anything. It surprised me and made them feel more alive. TS4 never really surprises me and thus I get bored easily. I haven't really played for months - I usually just make a sim, build a house and play for a maximum of a few hours, then abandon the save.
EA says that now we are in control and we have the power of causing mayhem if we want to and avoid it if we don't, but that is flawed. Imagine you are playing a fantasy war game, but you get a notification that no wars will happen unless you make them happen. Now you make a war but you win easily every time because the game is rigged so you always control. What is the point? Total control means that you get no gratification when something happens, because there were no obstacles or challenges - you simply clicked your way into what you wanted, boring. If it was easy to win a gold medal in athletics, people wouldn't feel a sense of true achievement when they accomplish it.
Danger and Drama won't make the game 100% complete for me because the sims themselves need more depth (traits need an overhual, whims more relevant, likes/dislikes, turn-ons/offs etc.), but it will certainly help A LOT to bring back some of the charm from older sims games and re-introduce an antagonist (consequenses), because TS4 is like a movie without an antagonist: everything stays the same, the characters don't encounter difficulties and thus they don't experience development, etc. Even shows for toddlers have drama! (Ex. the duck doesn't like the cat, so now they don't get along and mischief happens etc.) Add some consequense and drama and you'll be so amazed that you'll wonder if it is still the same game.
