some of the suggestions in the OP are in some sense worse, because they either want to change things (story, characters, endings) that are the way they are in the game intentionally, or are just asking for too much.
You know for a fact all of it is there intentionally? Would contradict a recent interview where CDPR explains they were so engrossed with the open world, by the time they reached the last chapter of the game it was too late to develop it deeper. From memory they were particularly referring to the Wild Hunt and Eredin.
Given that the enhanced edition of the previous game only added 2 new quests (mainly to expand the short third chapter with more gameplay) and some better cutscenes, an overhaul of the last third of the game or a change to its fundamental narrative structure is unlikely to happen. It is also not reasonable to demand changes to how characters are portrayed (even if they are different from the books, they are likely different for a reason), or to the endings or other major events in the story. New characters will probably not be added to the game in cameo roles just because fans asked for them (they may still appear in a third expansion if one was going to be made after all). I also do not see the point in having "Yennefer of Vengerberg" on the list, why is there a need to add more of the character that already has the
most screen time in the game by far, and more importantly not incomplete or unfinished content in any way ? And if I recall correctly,
this particular suggestion has been rejected already by the developers.
It seems most of the popular points made by the community are causing your some ire, but keep in mind this topic is not about going into details on WHAT should be added to the Enhanced Edition, but WHY and HOW Enhanced Edition should and could be realized.
I personally do not think the ENTIRE third of the game can be redone, but I also think it's engaging and constructive to discuss it all in great details, and often passion, thus showing CDPR we're involved with their work, that we care about it and would love to see it be the best it can be.
It seems you've completely missed the point with Yennefer, but I have no intention on going deeper into that discussion. And I personally agree cameo appearance would not work, and that the expansions serve as a perfect distraction / continuation for those who've finished the main game. On that note, I'll remove that thread link, thanks for pointing it out.
Really, the bottom line is, all those threads, ideas and suggestions are there for CDPR to use, or not, as they see fit.
Better Witcher 2 save import would be good, although I think it is probably a low priority for CDPR. It would not be too hard to improve it so that at least dialogues react better to the imported choices, but it is unlikely that real meaningful consequences would be implemented.
It's a fine suggestion and one I'm sure it's been brought up, in particular the lack of Iorveth, Saskia, and Roche and Philipa inconsistency. Similar suggestions have been floating around, about Avallac'h, Eredin, Yennefer, Ciri etc. little dialogues/cut scenes that would offer extra goodness, without disrupting the main choice / consequence of the game.
I have not listed any technical suggestions in the OP, but I figured those will be refined over time, with or without EE. Although, suggestion for making Redkit2 available is probably the most significant in that area.
If you're keen to point out some threads you deem worthy of the EE cause, please feel free to do so. OP is there for everyone who would like to see EE become reality.
