Fighting ghouls with how they move now, how they react to being shot, and the added tension that all brings is fantastic.

I'd love an expansion that was feral ghoul based. In fact i'd love a whole game like that

That could be interesting. Imagine if it was co-op?

It would be like Call of Duty Zombies but with all the perks, and and items of Fallout.

1 enemy would get old, even variants of 1 enemy. people already complain there are so few types. A more ghoul based mission set would be good. Don't think too many focus on the ghoul menace as that was big in FO3, by NV ghouls were normalized. Ghoul attacks on settlements look cool if you can find the herd on its way into town in the foggy forest.
