All Ive been able to consider in my Fallout experience has been the extent to which a multiplayer aspect of Fallout 3 and New Vegas could be pretty sweet.
Lets get one thing straight right away, we need to keep it minimal. None of this Call of Duty (15+ players) BS, but a coinsiding story environment. Im talking 2 people, one wasteland.
Picture that the entire time youre exploring the different places around the Wasteland, you could either have a Multiplayer companion helping you through Deathclaws, Cazadores, and Mirelurks. Or, you could have a rival across the map working towards intersecting story portions where they try to bust your skull.
Think of all the crazy stuff you could do.
Example: One persons on top of Tenpenny Tower with the Experimental MIRV, other starts at megaton. GOOD LUCK! How far will the make it before theyre going in 32 directions at once? Wait..Wait!
So the question I'm posing is,
If an upcoming Fallout title were to release a Mutually beneficial Wasteland for you and a fellow gamer, What do you want to see from it?
