Have gaming friends that you don't like quite enough to splash out on? Quick, get them cut-price gaming presents! Or better yet, gamble on mystery gaming presents that they might not want! I know that's how I like to do my Christmas shopping, and GOG.com is facilitating by hosting its Big Winter Sale (opens in new tab).
There's half off stupidly good games like The Witcher 3 (opens in new tab) and Pillars of Eternity (opens in new tab), as well as even larger discounts on bundles of classics from the Star Wars franchise (opens in new tab) and Larian. The current batch of deals is scheduled to last about two days, but if you can't make up your mind, there's the intriguing option to try your luck on a £2/$3 'mystery game'. Presumably the refund policy won't cover that one...
