Bethesda are lucky in that they have a publisher who isn't pushing for a sequel every year or 2. That does mean longer waits for us between installments but we haven't had any debacles like Dragon Age 2.
I don't consider Dragon Age 2 a debacle by any measure. Sure, I think it is lacking a bigger world and bigger maps and some story elements but otherwise I liked it and enjoyed playing through it, more then once.
And I do not and never will agree with those who whine about Bethesda. If someone says "but Fallout 4/this other Bethesda game had bugs!" then that person really needs a slap from a reality. Because there isn't a SINGLE piece of software out there which didn't have bugs. And games like these are a gigantic piece of software which are incredibly complex so things do happen. Anyone who has ever really used software on any platform (and isn't a total schmuck) would understand this and know that patches will come along and fix things. That's a thing with every piece of software. For crying out loud, do we really need to say anything at all if a person is a Windows user (and most of people are)? Absolute most of those updates added constantly aren't "things to make it nicer and more comfortable", it's to fix yet another issue.
I personally never experienced almost any of the bugs in Fallout 4 what some people cry about. ONLY bug which I do experience - and many others - and which really gets my goat is the Pip-Boy reporting bug. You know, the one where in settlement in workshop mode all the settlement stats are OK, you leave it and check later the Pip-Boy and it tells that the water/power/food/bed is at 0 and happiness has dropped by friggin' 20 points and when you race over to settlement and go into workshop, then everything is OK. It's a bloody Pip-Boy display bug, settlement does have all the stuff, but that bug does affect the happiness. Wish that got fixed, or someone somehow would "disconnect" settlement happiness from Pip-Boy...
Other then that, I am actually very thankful to Bethesda. Not only because they make the games I've really liked for many years, but because they're making Fallout. Because I played Fallout 1 and Fallout 2 years and years ago and then there was nothing. I was absolutely sad and pretty sure that this was the last we've seen of Fallout, one of my most favorite gaming franchise, and then Bethesda got the license. And not only did they get it but they've released already two great games, bunch of DLC's for them and I liked all of those. And they're continuing to make more of Fallout. So as far as I am concerned, Bethesda is the savior of Fallout franchise and maker of great games and I only wish to them the best and hope that they keep making their games.
EDIT: Oh, and just to add, yes I also think that Bethesda needs either more/better writers or some lead story teller or whatever. Because Bethesda is a bit lacking in their "story telling", their stories aren't bad, but they don't have that "punch" either, you know, like Bioware stories used to have in the past (not anymore though, BW's going down the hill for years). If they could improve that, then it would really be a cherry on top of a cake.
