personally, i wish there were more bigger cities like l3el2nal2d mentioned.
More unique weapons would have been cool, and i wish they had a unique weapon skin too.
Personally, i dont like that the alien mothership takes fricken 10 shots from a deathray that can cause a crater from Niagra Falls to Lake Michigan :\
Someting else i dont like is that the quests are SO EASY once you do them. I like to do the same quests with different character styles, and find that aside from maybe crouch when i shoot or chainsawing, the way one goes about doing something is basically the same the whole time. Sure, you might be able to mow em down with a minigun then bypass them completely with a terminal hack, but the way the quest path goes is too similar. Thats maybe the one thing that Fallout 3 did not retain from Oblivion.
Apologies for DP...
The cars use nuclear reactors don't they? thats why they make a mushroom cloud when they blow up
They do use Nuke Reactors, but when you think about the fact that those cars have been sitting there for over two hundred years, with probably destroyed or corroded reactors, makes it unlikely for them to have survived.
