While I prefer the game's difficulty level as is, I can understand why people want this. I'd be perfectly fine with it being added in, especially if it's something I can opt into or out of. I personally love aspirations as they are in S4. I really loved S2, but I ran into a fair amount of aspiration failure that didn't always jive with the story I was trying to tell. I am primarily a story teller with this game. What I love about it most is how open it is to me using my creativity to make things happen. I'm deeply connected to the sims in my main save, so I don't feel like the game is lacking in difficulty (for me personally) because I've got my own challenges to play out. From a gameplay perspective though, I totally get why people get bored easily. If you're looking for game mechanics to offer challenges, you won't find it in this iteration of the franchise. I don't think that's necessarily a bad thing, but it is an obvious thing.
