Here's what:

Super weak weapon variety [especially compared to new vegas]
Paper-thin faction system
Exhaustingly bad story
Colossally dumbed down dialogues
Idiotic romance mechanic [not to mention six scenes, or to be more precise, lack thereof]
Abhorrent quest design
Lackluster city [Boston city centre was by far the worst place in the game, too cluttered with loadings etc.]

I see what you did there.... you sly dog you.

I dunno, Boston map is pretty darn dense man, I'm no longer a 95% pc, i7 4770k, 2xgtx780's, and only 8 gigs of ram, and I rarely have any load issues at all (then again I did make sure to install FO4 to my SSHD)

Yes, the loading screens were particularly annoying in the center. No BGS, I don't want to go through yet another loading screen to an area designed for PA skydiving because... I don't use PA...

Thank you for your contribution. There doesn't appear to be much room left for debate, so there's little reason to have this linger on.

Also, how about using only one account.
