Can I Run Sunless Sea?
Sunless Sea is an adventure indie game from Failbetter Games, released in 2015. Failbetter Games both developed and published it. It offers a single player campaign. At more than a decade old it predates every current graphics architecture, which helps compatibility and limits how well it exploits a modern card. Metacritic places it at 81. Completionists have 54 achievements to work through. Progress follows the account through Steam Cloud rather than sitting on one disk. Over 7 thousand players have left a Steam review, so this is a title whose performance is widely reported. Alongside Windows it also ships for macOS and Linux.
