I don't think you can know how a game feels without playing it. I've seen the vids and other material as well. I thought it could have been good but that's about all anyone could get from it.
Ah anyway sorry. I'm not trying to be contrary I want everyone to be happy with NV and don't want anyone to be let down.
"Everyone" being happy with anything made by anyone will never happen.
Someone will always have their own opinion, whether they consider the game to be good, bad, or indifferent.
I played Fallout. I found that it wasn't my favorite type of game, and didn't really care for it that much. I finished it. Since I bought the set, I installed and attempted Fallout 2. Never did manage to finish it because I disliked it more than Fallout. My opinion only; your mileage may vary. I found that, contrary to my initial expectations, I did end up liking Fallout 3. Even the original ending that so many people complained about.
