Speedruns are usually pretty damn quick.
As a frame of reference, speedrunners have managed to beat games like Dark Souls II in less than an hour . Know how long it took CD Projekt Red to beat The Witcher 3 the fastest way they know how?
25 hours. That's a freakin' speedrun .
The developers tell Gamereactor that by skipping the dialogue and taking the shortest possible path (which you certainly won't know when you sit down to play the game), they managed to finish up in 25 hours. But maybe that's not too surprising, as they've previously estimated that the game offers 100 hours of gameplay, and possibly double that amount if you wish to do absolutely everything.
And oh yeah, don't forget about the two expansion packs that add another 30 hours of gameplay. What are we supposed to do? Quit our jobs for the next year?
