I loved how it really separated my sims from the household to establish themselves as individuals. I always tried to adhere to longterm goals of my sims in S2, which meant adhering to their desired majors, greek life, etc. It always gave me a great structure to build their skills in line with their personality and wants, and when sending them back to the "real world" after graduating, generally gave me a great foundation for a generational subplot.
Honestly, after playing through generations of a specific family, I noticed my sims becoming smarter and more in tune with what was demanded of them coinciding with what they wanted. It made the game easier to play, but also more fun. It was hard to adjust to S4 without university, because it was such a rich character-building level of gameplay in S2 for me.
