It's really awesome. It has some biographies, and they talk about a couple of the rivalries (Bernard King vs Isiah) and the Knicks vs Heat, but they also have entire games, including game 5 vs Miami, game 3 vs Indy in '99 when LJ had the 4 point play, game 7 against Indy in '94 when we clinched the Eastern Conference, some huge games in the 80s, (Knicks vs Celtics) (Knicks vs Pistons) before the Era of Allanfan20 being a Knicks fan. And it also has a game 7 of the 1970 finals against the Fakers, which I'm convinced is as mythical as Poseidon and Zeus!
You should give it a look though. I saw the '99 games and it made me depressed about the piece of crap we have put on the floor now.
