CD Projekt are adamant that you don't necessarily need to have played The Witcher in order to enjoy The Witcher 2: Assassins Of Kings Enhanced Edition when it releases later this month. However, if you're interested, they've released a short cinematic recap video that brings new players up to speed with Geralt and his monster-slaying shenanigans. It's highly spoilerific.
It goes without saying that you should probably ignore this video and play the original game instead, so long as you've got a half-decent PC. It's a cracking RPG, and will ground you in the lore far better than any cinematic can.
The Witcher 2: Assassins Of Kings Enhanced Edition will release on April 17th for Xbox 360 and PC.
