Yes, yes, yes!I've not played any of the Witcher Games but have a new gaming PC on the way. Is it worth me playing all 3?
In all seriousness, it depends on your interests. Witcher 1 is old and has a strange control system, but the story is great. I 'think' there's talk of a remake.
Witcher 2 is great, but to me felt a bit grindy at times.
Witcher 3 is a masterpiece (in my opinion).
I don't think there's any need to do the first 2, but 3 I'd always recommend. I felt sad when it finished as I had nothing else like it to go to at the time
