I think we need more of a constant goal, something that can't be fulfilled. Not a box to be checked off. This could be represented in ranked clubs instead.
Like a country club for the wealthy, you'd need to be worth like, 5 million to join. 1 million would be too little, sims get that without trying.
And whoever is the richest sim would enjoy the most privileges here, so being the richest would be a constant goal. And this could really be this decadent snobbish club that looks down on poor people. Wealth determines their whole pecking order.
The country club could come with a golf course, and being a member could give access to buying some special things and special services. It would be all about living a life of decadent luxury and hoarding money.
Another club could be for geeks, it would be a friendlier environment where geek credits count. Doing geeky stuff, winning video games, building a lightsaber, getting the highest rank in any star wars organisation, etc. would build up geek credits. Members can geek out with each other. Aliens would get geek credits just for being an alien.
Their club house could be sort of a geek paradise with gaming consoles, board games, lightsaber battles, robot building, cosplay, etc.
And members could have access to special geeky stuff too not found elsewhere.
And yet another could be all about healthy living and exercise, giving access to some interesting objects to improve related skills and health.
Could be a club exclusive to supernatural creatures too, save for aliens. It would be focused on the more mythical beings. Mages, vampires, mermaids, ghosts and hopefully they will still add more.
More clubs are possible, and all could determine what wishes pop up for sims, that could replace the stupid useless wishes that sims get like wanting to buy a bee box because it's spring regardless of their traits or aspirations.
