Also there’s another at IGN VN, saying:
It’s obvious to me that fans of the series will undoubtedly love the game and newcomers will easily relate to the FPS and RPG elements present in Fallout 3. This is definitely one to add to your watched games list.
While The Escapist has another take on this:
I only got to see a fraction of Fallout 3’s possibilities, but I greatly enjoyed what I did see. That said, this is definitely a very different kind of Fallout. If you’ve never played the original games, you won’t notice the difference and will undoubtedly enjoy the game. Die-hard fans of Fallout 1 and 2, however, may feel a bit out of place in this new world.
Most of this was spotted at NMA.
