Oh, fucking hell. There's two Weekend Deals, one less painful to explain then the others.
The first is...
The other is up to 75% off various titles published by Focus Home Interactive. SO many good deals here it's insane. I'll list off what I think are the best.
One for Coolsome:

Includes Nemesis, Sherlock Holmes versus Jack the Ripper, The Awakened (Remastered edition), The Mystery of the Mummy, The Mystery of the Persian Carpet and The Silver Earring.
£7.49 / $8.74 / €8.74. Fucking hell, that's good value.
Another one I'd recommend if you don't already have it:

The three Runaway games, The Next BIG Thing and Yesterday.
£11.24 / $14.99 / €14.99. SO much cheaper than buying them individually.
There's also Divinity 2: The Dragon Knight Saga, both Game of Thrones titles (which both suck, so ignore them), Cities XL 2011 and 2012 and, best of all, FARMING SIMULATOR 2013, at 75% off.
(Oh, and the fourth episode of something called The Walking Dead is out as well. No, me neither)
