The introduction to the game was quite atmospheric. Great music and cool pictures. It gave me a feeling of entering a post-apocalyptic work. I know the intro is not finished yet, but with some text in-between the pictures, I'd say it would work quite nicely. The pictures I enjoyed the most was those of the scenery, like Megaton and Washington D.C.
As for the game itself, I think it is a good start.
Looking forward to follow the future development of the game.
