ofcourse buggyness is a sore issue, but it really hasnt got much to do with sloppyness in most cases but more from lack of time, and also I think alot of it comes from the forgetfullness of players, in our heads the games of years past was perfect and bugfree, but in reality they were really just as buggy as games are now. I wouldnt say games have become sloppier(especially considering how much more advanced they are nowadays) but peoples expectations has gotten higher. but ofcourse, me as much as anyone would wish games were bugfree, but there really isnt a "fix bugs" button to press(if there is, please tell me where its located on the keyboard!)
that said, looking back, GRAW patched is ofcourse alot tighter than graw out of the box and ofcourse we would have wanted it to be as good as it is now from the start, but time time time doesnt always allow this.
