I enjoyed the rhythmic style combat of TW1 and overall I think it's a great game that hadn't quite found it's footing. TW3 makes good on all the promise TW1 had. TW2 was a different, shorter, more linear affair but it served as a stepping stone. I think the games evolved perfectly from one another and they perfected everything in 3. The combat, the atmosphere, the story, the worldbuilding. The Witcher is such a great series. They surely make another one in 5 years or so after Cyperpunk comes out, but I don't think Geralt is coming back. He's one of the greatest protagonists in gaming, for me, but he's earned his rest.
The only animes I've watched are Attack on Titan and Death Note. Both I really enjoyed and thought were phenomenal until about halfway through. The ending of Death Note especially. Oof.
