The listing, Nintendo 64 Game - NBA Jam '99 has ended.
I know nothing about this, never played it, so here is a review for you:
The game's bread and butter is its NBA play simulation mode. It's rich in features and options, the most notable being a fantasy draft in which you can rebuild the NBA with custom rosters, then trade and create players under a bonus points cap. The 80-plus plays are easy to customize and call on the fly.
The game plays well as a sim, if a little on the slow side. The control is very responsive, and the inclusion of icon passing and special-situation options caters to most gamers' playing styles. For instance, the ability to call for a screen is so easy that I found myself using it at least once every offensive trip. The computer AI on both sides of the ball is sharp: Computer players are aggressive stealers and shot blockers, plus there's lots of movement off the ball. Still, there's room for improvement. The free-throw shooting method gets points for originality, but it's an analog-based style that may irritate some gamers. Also, there's apparently no option to switch to the defender closest to the ball; instead you have to toggle through the roster, which is a burden.
Happy Bidding!
