Had a few hours on Blood and Wine, bloody heck it's good. The new region is something else that's for sure, doesn't make you want to re-visit Novigrad/Velen. There's enough to do, including Gwent for those whom play.
Only put in 4 hours so far, and thus have managed to visit most of the villages to unlock travel points, done a few main and side quests to name a few things.
Back on it on Thursday evening and over the weekend.
