I went to the A&M/tech exhibition game at UNT, and the Gonzaga/Tenn exhibition in Frisco a couple of years ago.
They were both regular games with refs. The only weird thing about the Gonzaga game was, if I'm not dreaming this, I could have sworn they let a few players keep playing even after technically fouling out.
Exhibitions are a great way to get cheap tickets close to the court.
