Why is University so wanted? Can someone tell me why? I've never played it myself so I'm interested.

imo, TS2 university was just amazing... the first few times. it was a great way to get my sims to develop more skills before adulthood, which was way too short to begin with (29 days to reach the top of career, max skills AND build a family???) so the university path was rly just a way for me to "buy time" for my sims. then theres also the bonus careers and the career boosts. i didnt get to play with TS3 uni much, and for some reason TS2 had me burned out. but yeah, it does get old eventually. by the third generation, i just left my game on 3x speed til midterms and finals exams.
