German publisher Daedalic Entertainment are currently running a publisher sale weekend promotion on Steam. The German adventure game specialist aren't limiting themselves to point-and-click adventures these days, even if we'd like to point out that Randal's Monday (75% off), Deponia: The Complete Journey (85% off) and The Whispered World (85% off) are among the better entries in the genre in recent years. For strategy-RPG fans the Blackguards games (both ones) can be picked up for just £7.99 (80% off).
Daedalic recently launched two games on Steam Early Access - the Viking-themed building game Valhalla Hills and frontier train trading bonanza Bounty Train - are both 20% off.
