What a complete and total joke. I was already himming and hawing, due to having played these to death and the price being a bit iffy, then I read this, and the whole thing is torpedoed. Wouldn't even buy it dirt-cheap in a future sale. Bethesda can take their registration process, with their account, and cram it with walnuts. Right now the most interesting thing about them is the competition they're having with themselves to see if they suck more as a developer or a publisher.
What makes it worse, is that their service is basically non existent, because you can see how well that went for games sold on their own, extremely bare-bones client, let alone Fallout 76 and their service.
I do have a beth account, primarily for ESO (technically Zenimax) and once for a one time gander at Fallout 4's workshop, but apart from that, I've no reason nor any desire to use that crappy service.
The fact they willingly tied this to 3, well known, well played and most played as an SP game, just shows that they are more than willing to cram as many people onto their service, so they can likely pull a "hey guys, didja hear, we've got 50 million accounts, look at how popular we are, and how everyone is willingly flocking towards our online service!".
Ubisoft recently stated an increase on their Uplay service, but that was very much due to the fact that not many wanted to download and install EGS, and instead opting for Uplay, which a good number of PC systems, will already have installed and registered.
To them it's exciting and a bold strategy, but it's downright scummy to me, because I don't want a game being tied to a crappy always online based service, specially for 3 ancient games, which I played all completely offline, back in the day. There's virtually no reason for them to do this, other than to shove us onto their online network service.
I myself, was wanting to buy the collection on Switch, because I'd love to play all 3 on the go, in bed etc, but even though I already have a Beth account, I'm irked because it means I won't be able to play those games, fully free of some form of DRM, so it's a no go from me as well.
Basically, don't enforce your own crappy services where they don't belong, let alone on older titles, that have long since outlived needing any form of a network/service for them.
