Spore lets you take an extremely high-concept journey from a single-cell life form swimming through the seas to a continent-spanning superpower to the overlord of a galactic empire. Over the course of about five hours, you shepherd your critter through four introductory stages; then you leave for space.
We liked Crysis. Despite its less-than-stellar AI, annoying alien baddies, and flawed final mission, we liked it. We liked the game for its wide-open jungle combat and the power and flexibility the nano-suit gave us to approach combat any way we wanted. Whether we wanted to skulk through the jungle, shooting enemies half a klick away with a silenced rifle, or get up close and personal by throwing our enemies through the nearest wall, the game accommodated pretty much any play style.
