I'd really like to get the Partaeus Maximus statue one day. I missed out on getting the Limited Edition version of University Life when it came out. I'd be willing to re-buy the expansion just for the masquerades and toga parties
(I know it's kind of a waste of money but I'm a Sims stan), and I think people that never bought the Sims 3 before might be interested if these were ever re-released. I'm sure the Showtime LE version can't be re-released due to copyrights, but I don't see why the rest of the expansions can't have another sale.
Perhaps it could be a limited time sale of them to celebrate the anniversary of Sims 3 or for the Sims Franchise's anniversary, that way it's still exclusive items. People would just have another chance to get them.

I just wanted to throw that suggestion out there~
