Ive been playing many RPG's lately including Fallout 3, and New vegas but i also played Borderlands.
Your probably wondering "how does borderlands tie into Fallout?" well there is co-op in borderlands and i was
thinking with about 5 of my friends who play fallout and other RPG's how much funner would fallout be with an added co-op option kind of like borderlands. i know it might be a little over-the-top with the size of fallout, and im not sure if the developers have given thought into this subject.
