What would be the best spinoff of the MGS series to be started (maybe exclusive to) the 360? gimme best case scenarios, like which part of the saga involving which characters?
Well, Raiden's story from MGS2 to MGS4 is a great source for a spin off. So they could explore that, showing the journey from Raiden post Mgs2 to Raiden MGS4.
I personally would love to see a new main character, as we see in MGS4, FOX hound has been restarted, so why not have a new character? Would love to see a "bad guy" playing for the good team in Fox Hound, set during the MGS2/MGS4 events. Heck Snake could even appear.
A bad mothafucka, none of that "green" shit, or "metal gearrrr?" shit anymore, a cold ass son of a gun. And then give him his own series. Like Jedi Outcast.
