The Witcher 2 planted the seed. It depicted one of the most beautiful and brutal places you can explore within the whole of games, and planted within it an intriguing political story and a vicious combat system that made shedding blood feel physically and emotionally exhausting.
The Witcher 3: Wild Hunt’s exponentially larger world and new characters would seem to bear the fruits of that initial seed. A stunning and vast landscape, filled with difficult decisions and colossal creatures, awaits us, and it’s difficult not to tremble when you imagine the possibilities. --

The Witcher 3: Wild Hunt concludes the story of the witcher Geralt of Rivia, the series' protagonist, whose story to date has been covered in the previous versions. Continuing from The Witcher 2, the ones who sought to use Geralt are now gone. Geralt seeks to embark on a new and personal mission, whilst the world order itself is coming to a change. Geralt's new mission comes in dark times as the mysterious and otherworldly army known as the Wild Hunt invades the Northern Kingdoms, leaving only blood soaked earth and fiery ruin in its wake; and it seems the Witcher is the key to stopping their cataclysmic rampage.
CD Projekt RED has said that it is not necessary to have played the previous games to fully enjoy Wild Hunt. While similar to the previous Witcher games, Wild Hunt has improved on several aspects from past games. Combat revolves around an action role-playing game system combined with the use of magic. The fighting system has been completely been revamped.[9] Wild Hunt introduces some new mechanics, such as witcher-sense, combat on horseback, and at sea, swimming underwater, and using a crossbow. Additionally, Geralt can now jump, climb, and vault over smaller obstacles. The climbing mechanics have been described as "not exactly" like Assassin's Creed, but more "similar to what we have in Uncharted." Item creation and potion brewing still remains as in previous games, but has been modified from The Witcher 2. There are 10 witcher signs, 5 original ones, each having an alternative form along with the original ones.
The setting is more than "30 times larger" than previous Witcher games,requiring players to use a sailboat to some locations and ride by horseback to others. However, fast travelling around the areas of known locations are also possible.[13] The Witcher 3 has been described as "20% bigger than [The Elder Scrolls V: Skyrim]".
Each action the player does will affect the world; every quest has a plethora of options on how to complete it, and every outcome is different each time. CD Projekt RED anticipates approximately 100 hours for the completion of the game, 50 of them belonging to side quests, and 50 belonging to the main story line.
The game features a dynamic day and night system, realistic AI, responsive and dynamic environments. The day and night cycle will influence some monsters and their powers, similar to how a werewolf would gain powers during the night of a full moon.
Ciri, an exceptional swordfighter with mythical powers, will be a playable character for part of the game.
