Actually, I have another item that could be changed if they were inclined to do so. I doubt they would do it because it would require having to have the voice actors come back to record new lines. Just about everything that has to deal with the Reason of State Quest. Dijkstra, in the books, and for most of the base game, is a spy without asperations to be a ruler. He was a man that loved serving his King.
There would still be a reason why he would want Radovid dead, for Adda to be the ruling Queen of Redania and Temeria. Change it to where that could be an outcome if you side with Dijkstra without killing Roche, Ves & Thaler as one of the options. And if Roche and the others don't like a merge Redania & Temeria where you have to kill Dijkstra, then let it state that it was an unknown Doppler that took the form of Dijkstra sometime after seeing the ship full of Mages sail away and before you see him again in the warehouse at the docks. The real Dijkstra, well, his whereabouts is still unknown. Oh, wait, the unknown Doppler could be the friend of the Doppler you have to track in Novigrad. THAT could work out better, knowing that since you didn't have a reason to track down that Doppler's friend, the Doppler became Dijkstra out of revenge against you. THAT, is a perfect explanation for Dijkstra's 180.
And something else, more consequences for the choices that was made during the first 2 games. Roche and Ves not saying anything if you sided with the squirrels? Fat chance of that happening. Triss not saying anything if you didn't save her and Letho did? She's as spiteful as Yennefer. Compound that with giving Alvin to Shani, if you went that way, Triss should be pretty pissed off when seeing Geralt in Novigrad for the first time. Voice lines can be created for inside the granary, for Geralt to either hash it out with Triss (for romance), or to blow it off or, better yet, bluntly telling Triss that she was using him anyway, so why would that matter anymore (for Yennefer romance).
There are a lot of consequences to be worked out from the 2 games that could be dealt with if this is truly going to be the last Witcher game with Geralt. So, make us pay for all of the choices we made. Don't let us off the hook. Not only would it be a fitting end to the game but, it would also make us want to replay the games again to get different outcomes to the final one.
One last thing, allow transfer of saved TW2 endings for the console users to carry over like it is with PC. I know the first game wasn't a console game but, that doesn't mean that it can't work without the choices from it. You can make the AI smart enough to figure out how a player played the 2nd game, to come to a conclusion on what the choices would be if the 1st game was on consoles.
I think that's it........oh wait.......did I mention the actual REDKit for the game should come with this upgrade?
