That having been said, I have friends who play Fallout, Morrowind and Oblivion too and while it is nice to hear what they did in their games, I would really like to go around the worlds with them. Turning Fallout 3 or New Vegas into an MMO would be awful in my opinion. Don't believe me, play Fallen Earth and you will. What I would like to see is a game of Fallout New Vegas which looks and plays almost exactly the same as now except make it so that maybe up to 5 people can play the game at the same time.
The only aspect of the game that would need any real tweaking would be the interaction with computer controlled characters. When you first build a character there could be a choice of different voices. Then when you interact with an computer character you would not only hear their response but you would hear yourself asking the question. This way any other character within hearing range would still gain info from the conversation as though they had the conversation themself. The benefit of doing it this way would be that you would not need every person in the game to repeat the same conversation just so that they all get on the same quest.
I think this could be a lot of fun. I don't know if it is actually possible but if it were it would add an interesting element to the game. The Fallout world would be more fun to explore in a group rather than as an individual.
What do people think? Is this possible? And if it is, would anyone be interested in it?
