I think allot of people would enjoy playing a new fallout that is back to the roots of the original 2 fallout's which were probably most peoples favorites I would assume except younger members who might like the newer ones more on the count of better graphics etc.
Even to build a new game on the old fallout 2 engine would be awesome to have a new adventure and stuff to do in the old game the wackiness and darkness of the first 2 games was great and how unforgiving the game was as well.
