I'm on my 4th play thru of RedDead2 so it is time to begin something new.
I want to begin Witcher3 on the XBox1 but my kids tell me since I've not played the other Witcher games I should either read the books or watch the TV show first. They think it will make much more sense to me that way.
Agree/disagree?
It depends on how much you tend to care about the relationships between characters and the backstory of the world.
I had read none of the stories or played the games before I started Witcher 3.
I skimmed the wikipedia page for the plot of the second one because there is a point early in Witcher 3 where you recap the "choices" you made in the previous game and I wanted to chose the options I would have if I had played the game, but that's about it.
The game has a glossary that will add character bios as you meet them that is pretty in depth as well.
