I had one playthrough of 90 hours+, wich became unplayable. The savefiles were corrupted. Next playthrough I got the infamous loading crash bugs, wich meant I wasted another 40 hours+ playthrough. You can check the forum here and see there are loads of other people who have the same problems.
That is no fun at all. These are the things that scare me indeed. But if I understand you correctly, all savefiles are corrupted? It's not like you can load an older savefile and play on? That save file will also get corrupted after a while?
Of course it would scare you.
But read the post again:
90+ hours and savegames became currupt. 90+ hours.
40+ hours after that and there was a loading crash bug.
Still gives 130+ hours of fun.
Also remember that people complaining about bugs are sometimes VERY vocal everywhere they can think of.
The thousands of player that hasn't experienced bugs are often silent.
Have you tried following some of the Youtube channels where they record complete playthroughs?
They couldn't if the game was as broken as some will suggest.
Some of the bugs are merely small irritating things that are blown out of proportions.
Consider a bug, where a quest journal doesn't get updated to reflect a certain meeting. I've seen it mentioned as "game breaking".
We can deduce that "game breaking" is dependent on the player.
This does not mean there are no real game breaking bugs. But they get fewer after each patch.
And some bugs ONLY surface if certain criteria are met. "Have you killed this bloke, robbed that one, broken this container and used this wand then AAARRRGGGHHH."
