I actually had a lot of fun with the shooting, and that's partly why I played so damn much of it. The crafting/building is the other part. I have a bunch of power armor and never really felt the need to wear it, especially once I got access to ballistic weave to make regular clothing awesome armor. Finished it yesterday at 79 hours. I'm glad I'm done because I was at the point where I would still pick up everything even though I knew I wasn't going to do anything with it. The same thing happened with weapons, I was carrying way more than I needed to, just because I had every single type of weapon/ammo and wanted the option.
There is one location I'm still interested in clearing because it has robot pirates.
