Every store in this table quotes us in euros, so the EUR figure is the price the seller actually set, not our arithmetic — which is why EUR is also the currency we rank in. We only list an offer here when the store gives us its price in euros, so nothing in this table is a number we invented.
Pick USD, PLN, GBP, CAD or AUD in the header and we convert from EUR at the European Central Bank reference rate — converted amounts are prefixed with ~. Your bank or the store may apply a different rate at checkout. We never hide offers based on where you are: everyone sees this whole table.
We may earn a commission when you buy games through links on this page — at no extra cost to you. It never affects our rankings or verdicts.

About Cthulhu: The Cosmic Abyss - R'lyeh Edition
The store page frames R'lyeh Edition as the deluxe treatment, and it partly is, but this is an add-on bundle that needs Cthulhu: The Cosmic Abyss installed to do anything at all. What you actually unlock is a side quest called The Shining Trapezohedron, a standalone Arkham Horror tabletop RPG scenario, a non-Euclidean artbook and the eldritch soundtrack. The listing text trails off after that, so check the store page for the complete item list. This is bonus content and digital extras rather than a new campaign, so it lands squarely with completionists who finished the base game and anyone curious enough to read the tabletop scenario. If you bounced off the original, nothing here will pull you back.
