When the third one was announced as coming soon, I decided to play the first one... Which didn't last long. It was bad. I won't comment on the story, because I never got far enough into it to experience it.
So I gave up. I didn't bother with the second, but since everyone seemed to like the third so much I thought I would start there. The intro was okay, but I can't say I really liked the character, the story, or the general universe.
Then I got into combat, and it seemed stupid. Rolling around. Hand magic. The feel of the combat just felt off, and I decided not to bother playing.
The story seems like one of the strongest points, but when I disliked the combat and interface so much, I didn't get to experience it.
I have played the Game of Thrones RPG from Cyanide. It has been pretty universal panned as terrible, but I enjoyed it. Mors is a very similar character to Geralt, old, gray, veteran, but I liked him a lot more. The game has a lot of limitations, but I really enjoyed the story and the combat was okay, and I enjoyed creating character builds. So the game itself was fun, the story was good, although not perfect, but good, and I liked the universe and characters. With Geralt and the Witcher universe, none of those things were true for me.
