DriveClub. Tons of tiny details and the huge after launch support brought with it free cars and major gameplay changes. The weather patch alone added a huge visual boost to an already unbelievably realistic game. Photo-mode added tons of replayability for those looking to capture every tiny detail. Rainbow.s are realistically generated in realtime taking the suns position and rain position/density into account. Heat haze (which also takes the suns positioning and the environments temperature into account) was also added in the latest patch further seating the visuals in reality.The AI was tweeked so they don't reach ridiculous speeds drafting off players and other opponents. Crash physics bug fixed. The online was also fixed fairly quickly looking at other 2014 releases (though it should have been working at launch).
Honorable mentions include Uncharted 3, Ratchet & Clank: Into The Nexus and Donkey Kong Country 3D.
