I wonder if hacking off pieces of act3 is �the last minute crisis� that Sven mentioned in
the FPS podcast.As a software engineer myself I think it is possible that there was something really nasty going on at some "critical point" in Upper City that the whole part had to be put aside for the time being. If the access to Avernus happens in Upper City, too, then this may be a reason.
I can also imagine that the missing epilogue has something to do with this as well, maybe it simply made no sense having the epilogue in there while Upper City is not part of the game.
Notice how I say "put aside for the time being" and "while".
I wouldn't rule out that patch 1 and / or 2 bring back the meaningful parts of the content that is currently missing.
That would be my guess. I haven't seen act3 for myself yet, but upper city, and variations in the epilogue/ending slides are things I am pretty confident Sven mentioned himself.
I don't think such major addition will happen soon though. I suspect that if it will happen, it will be in a form of their usual "Enhanced Edition" a year or so from now.
Not sure how to feel about this. On the one hand I desperately want Act 3 to be polished and I am all for more content, but if they add in cut content with patches, it means that they knowingly sold an incomplete game...
I think every game is technically incomplete, as things always get cut, sometimes to the benefit, sometimes to the detriment of a game. The only difference here is transparency, and I really don't think one can condemn Larian for being transparent. In fact, common complaint has been that they weren't transparent enough - that's the reason why. You mentioned you work on something for the game, and you don't deliver, audience will be understandably disappointed.
Larian doesn't have a habit of charging for their patched, so if something forced them to remove planned content for 1.0, it is commendible if they are willing to spend resource to finish those. Other than wanting to deliver the best game possible, they have no incentive to do so.
