The Witcher I really consider it as a very replayable game but between future times, being a very long game and completing it, and then at the same time playing it again at least to me it doesn't seem like a great idea, I think it's best to wait a while to forget things to experience everything again and create a new story with any of the other endings. I haven't seen the series yet, but what I've heard is that it's very good and that its story is not as linear as the games, but much more direct to the books.
