made by the same people,same game engine
Same peeps, same engine, lots of similar concepts (like skills and leveling). But also a lot of new things that set it apart, plus the whole game setting is different.
I played it for four hours last night (which is how long it took me to just create a character and get out of the vault). I was impressed by the new features, but I miss the green outdoors of Oblivion. The wasteland is just that, a fukin shitty wasteland.
Bottom line though if you liked oblivion you will love this. If you dont like oblivion or haven't played it but like huge games with tons of customization and endless options, you'll like this too. The fact that I played oblivion for years and was still doing new things means I'll be doin the same with Fallout so yea, you get your skrills worth.
