Yeah I was disappointed with Radovid too, turning him into a silly madman just reeked of Bioware writing (Orsino, Meredith anyone?)
Thankfully this Radovid doesn't have a big role in the game
But he was kind of a big deal in
Witcher 2 and that's why it blows extra hard. Same with Letho but I killed him, and the second I heard he was in
Witcher 3 and had a questline with Geralt I couldn't believe it, because I'm pretty sure Geralt said something like "go away, far away so I won't see you again" if you let him go at the end of
Witcher 2. There was no way these two could just bro it out like that.
I am disappointed with some major aspects of
Witcher 3 but I went in knowing there had been dishonesty from CDPR with the downgrade, I knew the lead writer was not the same etc. This simply wasn't gonna be the game every
Witcher 2 fan would want, so I lowered my expectations beforehand and got a rather spectacular game with wonderful and heartwarming cheracter-driven stories out of it.
The thing I am personally really sad about is how disrespectful CDPR were towards any of their endings and epilogues. Some things are unfixable, like Emhyr not having enough significance on the plot in the long run, but I desperately needed... something more to the climax before it just cut straight to the epilogue and started closing the plot before it felt ready to be doing that.
