Any game can crash or freeze. Some people will play a particular game and never experience a freeze. Others will experience multiple freezes. Some few. So it goes.

If you're waiting the reviews to see how bugged the game is(or even how good the game is),you're wasting your time.

Fallout is that type of franchise where the score range is already decided long before reviewers even get their hands on the game.

Doesn't matter how bugged the game is,they will ignore that(together with some basic design flaws like plot holes in the story,dumb down gameplay mechanics,etc...) and when the shitstorm start they will make some articles about it.(maybe calling people entitled)

Then when(if) the game keep having bugs and glitches for a long time,they will be forced to point that out(just like happened with fallout 3), but nobody will lower their score and even if they do metacritic will be already set and nothing will change.

Then years from now when the dust has settle and the hype googles drop off,people will start to point out all the design flaws and lack of polishness this game have that the "entitled" people from 2015 were talking about.Even some gaming sites like eurogamer will get some balls and talk about this(they did that this year for fallout 3...8 year late tho).

In the end, reviews are useless for games like fallout 'cause reviewers are historically in bed with the devs/franchise. Playing the game or at least watching somebody else play on twitch are the only options in this cases.
