I don't understand the justifications my friends come up with for continually doing this. I was playing Destiny with my friend and one of his friends and he mentioned that he almost finished paying off his pre-order for GOW4. When I asked him what he would do if that was a bad decision and it was a dud. He nonchalantly said he would trade it in. When I mentioned waiting for reviews, his freind, in a defensive, sort of offended tone stated reviews don't matter and you should decide for yourself weather you like it.
I mean, that's fine, I guess, but I think you should at least wait to see that the game isn't broken.
My friend also defended the AC game that launched a few years ago, stating that it was a new console and they didn't know how to work with it. One would wonder why they where willing to release the game and block reviews until after release. No, they knew exactly what they where doing.
And we wonder why we get so many broken games....
