Hey I took the comments you guys gave me and thought a bit about them and most of you said no to co-op but what if co-op was just an option not an all time thing, that way you can have your own game for single player and another game mode for co-op so that you can play both SP and MP. I would specifically like to thank phyrian for his comment on my other post...."The Fallout series are arguably one of (if not the) best single player games out there, and I would not want the addition of co-op or MP to change that. I would love to see the ability to have some kind of co-op play, but would not want any achievements, story lines, or add-ons that required it. It should be something purely optional". Thanks and reply.
