If you're on PC, VATS is on Q and you can widen the FOV through the use of the console. If you're not on PC, sorry about the FOV problem and check the controller settings, it should have it listed there. Source: I too missed the tool tip for VATs.
But yeah, so far 7 hours in, I'm liking it. Very few bugs as well, save for Dog falling through the floor once and an enemy just kinda falling from the sky. Runs pretty well as well, a definite improvement over the previous games. I also like the fact enemies now try and dodge your bullets instead of sponging them, and that feral ghouls are fucking ASSHOLES to deal with now. Nigh on shit myself when I turned the corner, saw two of them and about 6 more just appeared out of the walkway above me, then noticed they were actively dodging my shots.
Sold on the dialogue system as well. Sure, it's not in a list like the older games but you can still go digging to find out random shit that benefits you in no way what so ever.
