Say what? They were open world games in that they allowed you to go anywhere you want, whenever you want. You have to travel using a map, but the world is still your oyster.
I generally kind agree with Fallout 2 being better, but I still like Fallout 1 more. Fallout 2 improved the gameplay, but I enjoyed the story and locations in 1 a lot more. It was wacky, but not as over-the-top, bat-shit insane as Fallout 2.
