I have read a great deal of posts in this thread and have arrived at a couple of conclusions. The first of which, is that it is clear that this series has captivated quite a large audience and is by far one of the best games I have played in ten years. What makes this game great is the character depth and gripping story. Having these strengths, you can see why so many people were disappointed at the lack of closure pre-epilogue. The overwhelming support of this notion indicates that this is not a mere matter of opinion, but a legitimate blemish on the otherwise perfect game. Another conclusion that I have come to, is that the community as a whole would likely be put to rest by one simple thing, closure with the main characters. This could take the form of an ending dialogue pre-epilogue, or a final goodbye post-epilogue. Simply having them present in the game after the finish is all most of us are asking for. A final conclusion is that this fan base largely adores CDPR, but will become wary of future purchases since there is a track record of lacking polish on the final product.
In sum, I simply wanted to affirm what so many before me have said because I felt the exact same way at the end of the game. My goal is mainly to show support for this movement so that the developers continue to recognize it and maybe one day address it. I intend to be reasonably patient, as others have mentioned the game really hasn't been out for that long. I also want to show support for the developers, because I - like many others - would be extremely willing to pay more for for the patches and DLC if it meant having the proper character closure that we so desire.
The more people speak up, the more it will be recognized and at least acknowledged as an issue!
