Ive found that the reason is, people are stubborn most of the time.
A person can own a PS3, a decent gaming PC, and an Xbox, but will still get it on the PS3, or PC most of the time. They know theyre going to get the blunt of the glitches, and still get it for those systems anyway.
Im not trying to come off as mean, or call people "stupid". ((Even though many people can be.))
Im just trying to say, if you know its a Bethesda game, and all past Bethesda games have been buggy for PC or PS3, why get it if your going to complain about it? If you KNOW your going to get bugs, and you buy it anyway, you really shouldnt be complaining about it.
I have all 3 systems. I dont care if it would look better on my PS3, or i could mod it on the PC. I want my game bug free above all else. So i get it for the 360. Ive yet to encounter a bug that i would consider "bad" in anyway. The worst has been a corpse falling through the ground. Sure, i would have liked to l00t it xD but oh well. Im not going to complain about it, because i knew its something that can happen when i play a Bethesda game.
tl;dr:
You sleep with a vampire, dont be surprised if you wake up as one. Knowing your getting a buggy product, and then complaining about it doesnt get anyone anywhere. Saying, "It should have been released later" doesnt help either. They cant find every bug stretched across the entire world, nor every conflict with every PC setup under the golden sun.
Again, im sorry if this comes off as mean or something, as it was not my intention. But alot of the time, when people want to complain about something, they had measures to prevent it in the first place.
