I purchased 2K6 last night... I think they could have done better on the menu grafx, but the game play is pretty solid, and that is what counts.
The main problem I have so far is I don't like the play calling. I need to play around with the different options and experiment more with the plays. The passing is kind of buggy sometimes too. I pass in the direction of a player and instead of it going 6 feet to the player, it throws a 40 foot crosscourt pass at another player in the same "line". Of course the pass gets picked off too lol. I started using the trigger to call my passes to a certain player instead, but if you don't hit it in time you might end up shooting instead of passing to the "X" player
Another thing, I have found that certain players seem to take high-difficulty shots around the basket (not using shot stick). Some players try these crazy reverses instead of just going to the rim. When they make the shot it is cool, but when they miss it I feel like yanking them out of the game.
The shot stick is interesting. I need to play with that more too... It should be called "showboat stick" though imho
I think I need a few more nights before I can make a final judgement on this one...
