Even for coming out almost two years ago, this game still can give you hours of fun.
24/7 Road to the EBC is a fun mode that gives you a chance to create your own player and take him around the world to compete versus both NBA players and actual celebrities (i.e Flava Flav). The more victories you rack up, the more development points you receive. Franchise mode is a decent attempt to create a Dynasty, giving you full control over all of your teams needs, including Scouting, Practice and Transactions. It gets a bit repetitive though after several seasons
The Crib is a virtual "pad" that you can add memorabilia to once you gain some cash. And can become addictive after a short while.
Overall: If you don't feel like dishing out 40 - 60 bucks for the more recent NBA simulations, NBA 2k6 can be an adequate replacement
