Shadoworlds is an RPG created by Krisalis/Teque and released in 1992 as a sequel to Shadowlands. It was published by Domark.
While the predecessor was a classic fantasy RPG with some Japanese influence, Shadoworlds is set in a post-apocalyptic sci-fi world.
If the settings are changed, the game engine, characterized by a technology called Photoscaping that allows dynamic lights and shadows, is still the same. So it should not be surprising that the gameplay still requires the players to find torches to see the environment. Having played and completed the game, I can say I enjoyed these mechanics a lot.
Even though Shadowlands was somewhat more original, the color palette of Shadoworlds is more readable and makes life easier for the players. You still have some minor issues we had in the predecessor, e.g., the excessive micromanagement, but for some people, this is not a problem.
In short, maybe not be the best RPG out there, but Shadoworlds (like its predecessor Shadowlands) is a good game, highly recommended for fans of the genre.
