This is a story-driven game set in 3 parts, with a prelude, interludes, and a postlude.
The game is about two brothers who witness a new civilization come in contact with their own, the Incenders, a race of humanoid fiery beings. Over time, the brothers deal with a variety of forms of conflict.
The puzzles are a bit odd; the first big puzzle is serving drinks to a large group of people, and this can be tedious. It gets more exciting with dangerous exploration puzzles in parts 2 and 3.
A lot of world building has gone on here, similar to that on Worlds Apart, but on a smaller scale.
Recommended for fans of "hard sci-fi".
