Not changing the game does not mean that excellence can't be achieved.
The individual components of "Invisible, Inc." are not new: stealth-based gameplay, resource control, and a gameplay flow of "your turn, their turn". However, the premise, and how elegantly these components come together, is nothing short of art.
As the driving force of a spy organization on its last legs after some unknown infiltration, your last two agents must undertake missions around the world in a last-ditch attempt to regain capital and resources, in the form of bionic augments for your agents, buffs for your UI internet ICE program, Incognita, cool-as-the-other-side-of-the-pillow spytech, and cold hard cash for whatever else comes along.
The squad at Klei seemed to have considered everything, alllowing for your agents to lure the hapless security guards out of position for them to be avoided, subdued, or removed with extreme prejudice, according to your preference as a player. Offsetting this level of care, "Invisible, Inc." is BRUTAL. One mistake, and your agents will be spotted, cornered, and removed from play with one-shot-one-kill nonchalance.
From the art style, reminiscent of Nagel-gone-Tron, to the "let's play it again" gameplay, "Invisible, Inc. is a masterpiece, and is one of those games that infiltrates my thoughts while I'm away from the keyboard. Easily my frontrunner on my personal "Game of the Year" list, "Invisible, Inc." gets my highest recommendation.
