The last amazing game for me was Batman Arkham Asylum (2009). Fallout New Vegas (2010) and Enslaved (2010) were great too. Sleeping Dogs (2012) was the last new big game I enjoyed. It is official - the Dark Age started in 2013 and will continue for at least 7 years, even Vanga predicted this. You can call it the Age of Rehashed Games if you want, I allow it.
Deus Ex (2000) - a game that pushes the boundaries of what the video game medium is capable of to a degree unmatched to this very day.
