It has a better simulation engine for simulated games (i.e. all bench players dotn play 9 minutes each)
the simulation engine is good but at the end of the season it really pisses me off. i created some of the top rookies in this years draft and LeBron averaged 21 ppg, 9 rpg, and 9 apg so im thinkin that he should win the rookie of the year award for sure. but who happens to win it? T.J Ford who averaged 18 ppg and 14 apg. another thing that i have a problem with is, (if you havnt noticed yet just wait for the second season) there are no secondary positions so when the spurs signed jermain o'neal, instead of having a dangerous duo of him and duncan, he comes off the bench and some crappy created rookie is starting at center. i mean, its common sense.
it has coach trading and signing (which actually affects your game)
this feature is my favourite because it actually does help your team. the coachs skill is split up into three categories: offense, defense and teaching which are split up into three ratings:poor, average, good, or master.
this is perfect because if you feel your team needs to work on their D then get a defensive coach. or if you have a rookie prospect, get a master teacher who can up his rating during off season training (which IS in the game)
it has the ability to set your teams play style (offensive, defendsive, post up game, perimiter game, etc)
this is only aplies to your team though, you can pick the two top players you want your offense to run through or you can just leave one of both on auto. but for the cpu teams the player with a better offensive rating in certain areas will be the star. for instance, in my experience with the game, facing the pacers is unrealistic because everysingle game, reggie just shoots threes and some how dominates inside and jermaine will get 15 boards and only take 2 shot attempts in the whole game. in 2k3 cpu teams pretty much use their guards for everything.
The commentary is better then i thogth possible on a computer game
im gonna have to disagree with you here. if you miss a shot with a shooter such as carter they will say "the other team is lucky that didnt go in, usually he's 99% in." or somthing like that but then the next three you shoot they'll say "carter saw that he had an average defender on him but he's just and average shooter" the commentators contradict themselves.
Live has very few of these things, and to be honest this game with live graphics would be damn good..
i see what you mean. live could use alley-layups, off ballance shots (if your right side is facing the basket, you wont just jump and turn in mid air for a perfectly straight jump shot, instead the player will jump straight up from his position and let it go (kinda like Dirk), better looking turn around jumpers, and a much better post game e.g it needs the spin off turn around jumper that duncan and k.g have. all of these things would make Live king for sure. but there are certaing things that live kills 2k3 in... like dunks... ALL of 2k3's dunks are just before the semi circle (charge line) in the key, and nothing further. players will take off from just after the freethrow line and lay it in while clearly being high enough to slam it. but yet there are no free throw dunks. in my opinion, most of 2k3's dunks are garbage. sometimes they dont even slam when they are on a fast break just because of they're rating. mamadou n'dyai was on a fast break (why the hell he was, dont ask

) and got to the basket with no defender, here it comes a simple 3 feet from the net, its bound to be a power jam (7 feet tall, low ratings but 7 FEET TALL MAN) what does he do??? HE FADES AWAY!!! thats pathetic. hope live can capitalize on all the mistakes both games have made.
(sorry for the long post....got alot of time on my hands

haha)
