I would actually feel indifferent (which wasn't among the poll choices so I went for the middle one
)
EDIT: and then the poll was changed so my vote disappeared :turtle: (it was the "terrible" one)
You understand of course that the differences between Fo1/2 and FO3 aren't limited in the 'amount of dimensions' and the positioning of the camera...
Each game is designed a certain way so that its world, its graphics, skill system, controls, its overall gameplay etc. are combined and complement each other in order to achieve a desirable result.
Which means that each big and little thing, like, for example, the 'isometric' view of Fallout 1 is an important element that makes the game what it is.
I suppose you might be proposing a proper remake of the early games - which would require a lot of tweaking to work, including a complete redefining of the skill system for instance, which might eventually work, but it would completely cover FO3 to do so. I wouldn't be interested in that though... I have the originals, they work just fine. Well if it was a free mod I might give it a shot, though I'd expect that it'd be 'inferior' to all 3 games - as it would be built on the wrong foundation.
Otherwise if you are proposing a more 'conventional' mod, that would stick to a simple recreation of the early games' world and quests, I would be as interested in it as I am of every other FO3 mod (which, I admit, isn't much at all). And I would actually expect it to fail in several different areas - it might be too easy or too hard, too fast, too boring, too small etc.
