I'm in the minority, but I liked The Witcher 1 also. I thought the story and world building was pretty cool, the combat is a little different, but easy to get along with. It's not as expansive and dynamic as TW3, but it was still fun.
TW3 was just great. I still need to do the expansions, but the writing, world building, etc were all so good. Agree that it's one of the better RPGs in the past 15 years. The combat isn't as fluid as Dark Souls, but it also isn't as high consequence either if you screw up. I find it a lot lower stress to play.
TW2 was the weaker of the three IMO. It felt like there were parts of the story you'd miss if you didn't read the books and the whole thing just felt really short for some reason.
