#10 Starhawk
Defined as a "shooter game for the PS3" Starhawk is a lot more than just a shooter. As the spiritual successor to the vastly underrated but fantastic Warhawk, also for the PS3, Starhawk sees the addition of a full fledged single player mode that allows players to build structures in the midst of battle—combining real time strategy elements with action.
In Starhawk's universe, humanity is bent on exploring and colonizing outer space, which leads to the founding of a distant colony called the Frontier, upon which Rifters (or prospectors, really) pursue wealth and riches. It's essentially the Wild West, but in space.
