Tom Clancy's Ghost Recon - GameCube

You control a six-man squad, divided into two teams, and you have the opportunity to hand-pick your squad members (and their equipment) after each mission briefing. You can switch your point of view to any of the six active soldiers--the solider you control automatically becomes the leader of his team, while the other team operates according to orders you give via a map interface. Thus, you can move one team into a covering position, leave them with orders to provide cover fire, then lead the other team in to reach your objective. Or, break up your squad and try to achieve two objectives simultaneously.

The level of detail and realism is incredible, right down to the way the soldiers communicate in hushed tones and with gestures. The complexity of the game requires an elaborate controller setup that takes a while to get used to (luckily there are plenty of training missions designed to help you learn the multitude of movement, weapons, and command functions). Once you get the hang of it, you'll find it's worth the time spent in boot camp.--Maile Bohlmann
