They're giving Bullfrog's classic Dungeon Keeper away for free - the only actual free-to-play one in existence. They'll be running a promotion all weekend for games built for two.
Of course if you prefer to declare your love for all things Dungeons & Dragons, as that's perhaps the only 'love' some might know, then a special D&D sale is on too.
Dungeon Keeper Gold includes the original game as well as the Deeper Dungeons expansion and it's completely free for 48 hours. No micro-transactions for your soul or anything! Dungeon Keeper 2 meanwhile will be discounted to just $1.49 in the Valentine's Day sale.
Planescape: Torment, Neverwinter Nights 1 and 2, Baldur's Gate 1 and 2 are among the D&D promotions. These join a sale of competitive or co-operative multiplayer titles on sale, with both running until Sunday 16 February at 10:59 AM GMT.
