Each team member can be promoted and upgraded, RPG style, to improve his abilities with certain weapons, or to make him more adept at his speciality. This means that if he is breaking a safe or planting a bomb he'll do so faster giving you more time to perpetrate whatever felony you are prosecuting - and make his getaway before the police arrive.

The Godfather II frequently take the form of 'doing favours'. If you commit a crime for an individual they will scratch your back in some way. This may simply be by paying you in cash, which is always useful, but it may take the form of giving you vital intelligence about a member of a rival family, and this can enable you to take a Made Man down. These executions have to be done in the right way, or the target will recover and take his place back in the rival gang hierarchy.
With intel you glean from doing a favour, you can take the enemy down permanently. Take out enough rival gang members, and take over all of their rackets, and they'll retreat into their compound. Once they do that, you can mount a full assault, and eliminate them for good. Favours for city officials can result in them returning extremely useful services in return.
Don Control
Doing favours can often involve you being asked to smash or bomb your own rackets - especially when you control all the action in a certain part of a city. But that's part of the strategy; is the reward sufficient to justify the lost revenue? Without being able to make these difficult decisions, you can never become head Don - The Godfather.
The Godfather II is an incredibly complex and sophisticated game, but it manages to be so on a shockingly simple learning curve. The game is driven forward with a simple, clear objective, and a compelling narrative. But it also has a huge range of open-world flexibility. At any time you can be pursuing the central goal, or involved in any number of side missions based on the favour system.

Conclusion
The Godfather II is the thinking man's Grand Theft Auto. For players who find the latter a little too vague and meandering, GF II puts in place a compelling central narrative, and enriches it with a wealth of management and strategy elements to make one of the best games I've ever played.
