I hope, if or when we get the Uni pack, that it's more in deph than what we got in 2/3. Those were super centered in the time spent at the campus and very few centered in how the university experience was reflected in the remaining life of the sims. I would love to see carrers upgraded, with new levels that would only be achievable for sims that finished a degree,just like in real life. I've also love that all education stages, from primary school on, would be improved so that marks would really matter. At this moment i think that is completely useless to have your sims study hard at primary or secondary school cause it adds nothing.
