If the game is so great why are you on this forum shouldn't you be playing it?
The off chance that my words or other people's words reach Beth so that they don't dumb down Fallout 4 even further, at least that's my reason.
The thing is, if you really can't even find a short list of things you "like" about a game, it's likely that there's no way the company would change the game enough that you
would like it. It's not "well, I liked parts of it, but these other parts could be improved."
Not being able to list things you like about something strongly suggests that it's not something for you. That maybe, you should be looking for something you
do like, not wasting your time talking about something you don't like at all.

edit: I mean, sure - I can list several things that I think are flawed or could be improved. But if I literally didn't like anything about a game?
I wouldn't play it. Or even try to change it into something I
would play. (ex: pretty much everything I've heard about the Souls games doesn't sound like something that I would enjoy. But that doesn't mean I'm going to start talking about all the changes they need to make so that I'll like it. I just don't play those games.)
