After the roller coaster ending of Sons of the Patriots, you couldn't blame the most ardent Metal Gear fan for feeling emotionally drained. MGS4 had a grand mission to accomplish: the narrative needed to tie up all the loose ends of the series and put Solid Snake's story to rest.

As great as it was to see so much closure for the core cast of Metal Gear Solid, this approach left players in an unfamiliar state where they were happy to say goodbye to Solid Snake and crew. But a bigger question lingered after the close of MGS4: Where could the next game in the series possibly go?
