Excerpt: March Madness 06 features all of the same gameplay modes as last year - including online play, which is solid, if unspectacular. If you're a hardcore hoops fan, most of your time will be spent in the game's dynasty mode, which allows you to head up any Division 1 team in hopes of leading them to the NCAA tourney.
Conclusion: I may be in a minority by saying it, but do we really need a new sports installment every single year? I know that the teams and such change with every season, but with such little development time for a game, it's very hard to expect a "better" experience than what the previous year offered. For the most part that's something that suffers from.
