I've been keeping a close eye on Kingdom Come: Deliverance ever since I got the chance to see its branching questlines, complex armor system, and AI-driven combat encounters for myself. While some folks are mourning the 'death of the immersive sim,' Deliverance is set to keep the genre kicking, albeit under a much more realistic guise than most. 

To keep things realistic without sacrificing the modern conveniences most games come with nowadays, Deliverance even gives the immersive sim staple of quicksaving a medieval touch. You can save by sleeping, and autosaves will keep you from losing hours of progress, but in order to save on the spot anywhere in the world, you'll need to stock up on Saviour Schnapps, an alcoholic drink that lets you reload from the moment you down the sucker. See for yourself in the latest dev video above (it starts around the 13-minute mark).
