Everyone seems to overlook something that I think is quite obvious:
Fallout 1 & 2 with Fallout 3 engine? It
can't be done! It's not possible!
You can try... but the result will
not be FO1&2.
It will be a completely different game only with some similarities on the surface.
You people honestly believe that the results of using an engine that different (such as the overall different atmosphere, the battle experience, and even the looks etc.) are so inconsequential?
It will be absolutely nothing like the original Fallout experience - could be good or great or even much better (it's beyond my point to argue potential quality
) but still... absolutely nothing like the original Fallout experience.
So, if you want to experience the classic Fallouts, your one and only viable option is to play the classic Fallouts.
