Full Campaign Co-op?

I am predicting a full co-op campaign in ME4 or at least a full stand alone co-op campaign. Similar to what is in Dead Space 3. Works very very well with DS3 so it will be interresting to see how it works with ME4. I know they will be considering some
type of co-op campaign for sure. Even if its a stand alone co-op campaign and a stand alone single player campaign.

Co-op campaign is the only mode I would barely be interresed in . But there is no way the Skyrim Bethesda engine could handle a full co-op campaign. They would have to dumb down the graphics or the content to be able to have full co-op. So I would rather
have this epic single player Skyrim experience over a washed out Skyrim co-op experience. And thats coming from someone that loves co-op campaign games. But there are just some games where it will never work. Skyrim is one of them.

.

Fable 3 is the perfect example of how they had to dumb down the game to make it work for a true full co-op campaign online. Fable 2 was such a great game but had a terrible co-op. So they made the co-op better but to do that they removed a LOT of the features
from Fable 2. As I said, some games just cant handle a true full co-op campaign experience. Maybe on the next xbox but its just not happening on the 360. The hardware cant handle it.

I am really hoping for a full co-op campaign. But if not then make some really really good co-op missions to enjoy.

I'd rather the campaign have full on 4 player co-op.

Is this a "full" co-op campaign or a stand alone co-op mode??? On the fence about buying this since I never played the other DS games. I am ONLY interrested in the co-op.
