How have you played your current or first character? No restrictions on spoilers. What about it had consumed you the most? If at all?
I glitched Preston Garvey somehow on my first character so after finishing with the railroad I restarted immediately, after finding out the game goes past level 50. I wanted to see what Preston does when not glitched and inactive. This time I'm playing as the mother like Darth Vader. Murder everything for Shaun. Still haven't seen what choices it leaves me with. Started with 10 agility and love playing like a melee/silenced pistol ninja.
SPOULERS kind of. Let me just say do not make the railroad your enemy until you've done enough missions for them and get the "ballistic weave" upgrade. This lets you put armor on clothes and hats of 110 balisitc and energy protection
I have almost exclusively followed the main story. After rescuing Preston I went straight to Diamond City ignoring everything else, and from there went directly to the subway to rescue Valentine, and from there to confront Kellogg.
The only other things I've done is Vault 81, and one of the sidequests (with Bobby De Luca) is bugged and that pissed me off enough that I stopped playing until they release some patches.
Honestly, the game has failed to grab me in any meaningful sense. I loved the first three games, New Vegas took me a while to get into, and 4 just feels kinda lifeless. The game world looks amazing, but it's not alive enough.
