The Elder Scrolls: Skyrim

This isn't just a game - it's a masterpiece - a very large sandbox game that rejects the quality-quantity inverse proportionality. By genre, TES: Skyrim is a role-playing game - it combines some of the best elements of older titles in the franchise with some new sandbox elements to churn out an extremely engaging and addictive game. It makes use of Bethesda's Creation Engine which isn't visually intensive in that it doesn't use taxing graphics features. Instead, the game's presentation itself, with large open worlds, ends up taxing your hardware. Faster GPUs result in smoother gameplay with most eye candy turned on.
