Well Area 51 would be cool my only qualm with it would be the fact that they would probably do some [censored] alien DLC with it, if they were going to have a DLC like that I'd love to have something more original because everyone always associates Area 51 with some extra terrestrial life or UFOs or something else stupid along those lines.
How about a DLC relating to the fact that its an Air Force Training and Testing Ground for new Aircraft? Maybe some secret weapon the U.S. was cooking up for the war?
Anything but another alien DLC, Mothership Zeta was god awful.
Well my idea doesnt have Area 51 as an alien strewn house of horrors type facility. My idea was a facility with atleast 50 levels (floors) going under ground and each floor was dedicated to a different area of research. One level would be on research on ETB`s, one would be on research of extraterrestial science research, one level would be on energy weapon research, one level could be on military vehicles (land/air/sea), ect. This way as I was thinking as we move along the facility it is always changing its never just one topic throughout. In real life Area 51 is pretty much the same way.
Personally if we could get it as an expansion to make things even bigger I would prefer this but since area 51 is situated in a dry lakebed in a valley surrounded by mountains theres not much room so a DLC would be the only logical choice.
If I had the time and the ability to I would download the geck and make my own underground bunker for FO3 and make it just like Area 51 but give it another name.
