Greetings from Lithuania.
Oh, my, God. What a game, What an adventure. "The Witcher III" is easily the best game not only in 2015, it is one of the few very best games i have ever played. To write about all ~100 hours + that i have played through till finishing the story would need more then 1 page, so i try to be short as possible.
Probably never before i was captivated by open world then in this game. It is huge. And i mean HUGE! There a tons of activities, and every one of them is interesting, it keeps you going further, explore and etc. Gameplay is outstanding. Fights are incredibly done, they are brutal, so as this world. Graphics are amazing. Music! What a score and especially during battles - great stuff. Voice acting was superb by all involved. Just to thing how much effort was put into creating every single thing and detail in this game is mind blowing. To be honest i wasn't a fan of "Witcher II", haven't even played the first one. But after finishing "Wild Hunt" i can safely say - count me in for (hopefuly) next installments. This is simply one of the very best games ever created.
Overall, "The Witcher III: Wild Hunt" is a masterpiece. I do not use this word usually, but in this case it is the one that perfectly summarize this experience. Own this game no matter what genres do you prefer - this is a perfect game for everyone.
Masterpiece.
