So, this is going to sound awfully n00b, most likely, but I'm okay with that. I'm also well aware that I could google/etc and find answers to this, but I have no immediate need for an answer and it could be a decent discussion point here. So here we are.
I'm not into NCAA basketball. NBA is all I've ever watched or been interested in. Same goes for video games. I've never touched a NCAA game. NBA Live for years, and now the 2k series (and NBA Jam/Street/etc, but those are a whole different category, of course).
What are the main differences I would notice between the NBA games I/we are used to, and a NCAA game? I only know the basics like the differences in the length of the games/halves/etc.
I ask because I noticed NCAA games are dirt-cheap used at my local GameStop (the new one is only $19 after member discount), and was considering playing a player through college and then importing the draft class into NBA 2k8. But I don't want to do it if the differences are too great to be able to pick up the NCAA game and get into it fairly easily.
