God of war 2 and 3 ( 2 for biggest cliffhanger of all time lol)
MGS3 is the top for me because of how sad it was and showed that the boss was a true patriot all along and manly tears were shed when Snake visited her grave in Arlington and started crying when he saluted. The government really knows how to screw people over in the MGS universe.
Batman arkham city and infamous 2 endings were good as well.
I make it rain with Kudos
