A perfect game for all those nba fans out there.
In terms of realism, you can't find a more realistic NBA game right now. From Kobe's fadeaways to Steve Nash's fancy passes to Tracy McGrady's patented scissor-kick release, virtually every move these players make looks identical to the real thing. And while this won't be mistaken for an actual game of basketball, most of the players look enough alike to their real life counterparts to be easily recognizable. There are exceptions, though, where players will simply look hideous.
The game itself plays out in realistic fashion, with the inside game being the anchor for any good offense, while finding the lapse in a defense will properly reward you with a high percentage shot. Simply trying to dominate the game with a single player is much more difficult than in previous games thanks to the combination of lock-on defense and smarter defensive rotations - smarter, but still not quite smart. You'll still find yourself screaming at the screen when defenders watch someone drive right to the hoop and do nothing to stop them.
Likewise, while certain aspects of the game have taken tremendous leaps towards realism, others have done the exact opposite. Alley-oops, no matter how ludicrous the lob and actual dunk attempt, go in with such great frequency (so long as the passer has a decent pass rating) that you'll be tempted to simply run pick-and-rolls all game long. On the defensive side, double teams are almost a guaranteed take away for the defense (and the ballhandler doesn't even seem to care; he and the defender will just stand there, seemingly exerting no effort at all until the ball ends up in the defender's hands) unless you're lucky enough to see it coming and mash the pass button.
Shooting percentages are generally in the normal NBA range (if not on the high-end, usually), but this is only accomplished through what is quite possibly the most frustrating thing I have simply EVER encountered in a videogame: blown layups. Sure, they happen in the NBA from time to time, but the frequency that they occur in NBA 2K8 is just maddening. Fastbreak layups by future Hall of Famers like Kobe Bryant or LeBron James are botched like it's a bodily function, while the same will happen when taking a point blank layup with Tim Duncan or Kevin Garnett. I've actually lost a number of games due entirely to simple layups being missed in the closing seconds. And sadly, without them, the shooting percentages for each and every game would likely be in excess of 70%.
This year, by far, NBA 2K8 is the best NBA basketball game on store shelves. (Xbox 360, PS3) If you love basketball you must get this game.
