I think this college experience is really a PR thing. It's what you pay the most for and it is more entertainment than anything else.
Most countries' universities seem to work like the community college: it's near your high school, you go there and just study, the dorms for people from other cities are just cheap flat in the surrounding area, and you try to make your campus as small and focused on study as possible.
At least that's how it was in France, and my memories or universities are full of technical discoveries, amazing teachers and passionate friends. Not lifestyle changes, but intellectual ones.
The drinking games and parties, they stated at 16 and felt not very different at uni, just normal part of youth.
