well, ive only got 5 crashes in 40 hours of gameplay which i didnt find very bad (mostly it was my on fault since im playing without break for 4 hours or so)
no bugs with quest or companions. some minor graphical bugs, and sometimes a bad spawning (like you encounter 2 gaint rad scorps and then suddenly there spawned 6 more which caused me almost to have a heartattack

and yes my character died)
and well if your game runs smooth you dont have much to complain so you wont post it on this forum.
while if your game is buggy i can fully understand that you want a refund or want it fixed, and that is causing that the forums are flooded with rants and complaints. but the devs are working on it, which can take time. so patience is the key.
as for my self, i really like the game i think its better than fallout 3.
EDIT: i play on the xbox360
