I'll just make a very simple point here -
Many of the college games I've played (badik, mine, a few others I'm slightly embarrassed to admit to having played so I won't), are fairly similar to the college experience of myself, and quite a few others I know. Well - that is if you take out most of the main plotlines from these games.
That is - Lots of alcohol (regardless of your age), lots of drugs (Though not everyone partook, they were definitely around a-plenty), Lots of sex, pretty frequent parties (Although in my experience most were "small" in compared to how they tend to be portrayed. An average was maybe 4-7 people, exceeding that only a few times a year... granted you could argue 4 people isn't a party, but it was the way we did it!), and a lot of faculty being .... let's say fairly liberal in their application of rules and policies. (in particular pretty strict on the no cheating, pretty lax on the "no alcohol on campus"). Of course there was always that one who would enforce rules to the letter, but that wasn't the majority for sure.
In all honesty, if you just take what you see in these games, remove the "drama" of the main storylines (Not that there wasn't a ton of interpersonal drama, because there definitely was, but that's not usually what fuels the main story), and dial everything down a few notches, it starts to ring pretty true.
And If I'm being REALLY honest, if you compare anything in these games to high school, it REALLY makes me wonder what sort of high school YOU went to.
I'll note, I haven't played the game, so I'm only relying on the screenshots available in the game thread - but your normal graduate student (and law student by extension) is in their early 20s - and those screenshots seem to fit the bill pretty well IMO. Granted some people start later but... just a quick google search says the average starting age for law students is between 22-24, while the median age seems to be 26.
Again, I haven't played the game, so this is based on a handful of screenshots only.
