Ok, I’m sure nobody’s too surprised to see this one on my list! 😛
While I love the game’s beautiful ZX-Spectrum asthetic, the thing that makes this game so wonderful is how well that gels with its setting – you play as Jean Raymond, a Cathar monk in 13th century France. Scrolls scattered around tell the grisly tale of the expulsion by the Catholic Church one sentence at a time, working perfectly as both a storytelling and a gameplay device, holding everything together through some really powerful moments where the game and story break apart, and finally reunite.
L’Abbaye des Morts is free, and available to download for windows at locomalito’s site.
