Going to keep this short and simple, first I would like to preface I'm not a fanboy of the series, I picked Witcher 3 up because of the sale.

With that out of the way, Witcher 3 might be one of the best games I have ever played. Graphically it is beautiful, voice acting is great, and the story is like a good book you don't want to put down. Combat not only being superb has little strategic elements thrown in to help you in a tough fight like oiling your blade or taking a potion before a fight to give you an edge. The Witcher powers come in very handy in combat as well and are also useful in certain dialogue options. The Witcher 3 is hands down worth every penny you will spend on it, so I highly recommended it.

The only gripe I ever had was weapon and armor durablity making me travel far and wide for repairs breaking my questing.

DLC

I'm not covering the free DLC because that is entirely optional and obviously free. So the first DLC “Heart of Stone” I wasn't exactly gripped while playing it, just didn't have that flare the main campaign had to keep me entirely engaged. Sure there are definitely some good moments but what is added to the game doesn't really feel connected to you as the character. However, is it worth $10? Yeah, based on the time you will spend doing the missions and some of the extra gear you receive it is worth that cost. However, I would consider this DLC something to purchase if you want more things to do.

The second DLC “Blood and Wine” I really can't praise enough, it has everything you would want: a whole HUGE area to explore, some old characters revisited (never played the previous games, gathered the history from the dialogues an such), some decent fights, new loot, and a little humor here and there. However, for me the reason I was most satisfied by this final DLC is it wrapped up the story and gave me that satisfying conclusion that the main campaign epilogues didn't really do for me. If you have the money purchase this DLC without a doubt.
