With The Witcher 3 not to far off and looking pretty darn impressive, now would be a good time to catch up on the earlier games in the series. Steam has you covered by making both The Witcher and its sequel, The Witcher 2: Assassins of Kings, free this weekend.
If I were you, I'd head straight to the superior sequel to get a quick Witcher fix this weekend. Whilst both games benefited from generous post-release patches, The Witcher 2 is still the better of the two. If the adventures of Geralt are impressing you, then you can buy both games for 80 percent off until late on Sunday. The Witcher is £1.39/$1.99 and the sequel is £2.99/$3.99.
