Developers have taken great care to make an interesting story, but what really pulls you in is the dialogue and character interactions. They're made great through excellent writing, stellar voice-overs, and great body language. The characters on-screen may feel like real people, so it's very easy to forget you're playing a game and not watching a TV series.

The Witcher 3 is how an AAA title should play, sound, and feel like. Its deep combat, beautiful graphics, amazing sound, interesting quests, immersive story, and almost every other aspect of the game has a surprising amount of polish.

The total size of Witcher 3's world is about 52 square miles, which is 3.5 times larger than Skyrim and 1.5 times larger than Grand Theft Auto V. Thanks to the sheer size you feel like you're in a real world and not a constrained box.

The Witcher 3 has three completely different endings. The decisions during main quests and side-quests affect how the endings play out, adding up 36 possible outcomes. It feels refreshing to actually impact your character's fate and not just trot along a path to an inevitable conclusion.

There are almost no lazy "go get me 12 turtle shells" quests in the Witcher 3 and you get to experience some amazing writing even in the most obscure side quests.

You can just walk around for hours, find abandoned structures, caves, etc and find interesting side quests to do.

The world is intimidatingly massive but thankfully there are ways to cut down on travel time. You can ride a horse, use a boat, or just simply fast travel to explored locations. This makes the experience more accessible and enjoyable as a whole.
