I just don't see why people are still excited about Metal Gear. The main series is over isn't it?
no Revengeance extends the story :)
Someone's info is a little outdated it seems.
Rising continues the main MGS story but you play as Raiden.
Solid Snake is long dead by the time the events of Rising happen.
Its still a spin off though but its also still cannon.
Pretty sure Rising is non-canon. It's an alternate universe. Now Ground Zero is canon.
rising is non-canon to some extent. i know it has been scrapped and then changed completely, but i think the plot stayed somewhat the same. it's not after metal gear solid 4, it happens a few years earlier.
