No revenue estimate for GOG — its rating/review counts don't calibrate to sales the way Steam's do. The Steam version is estimated at $787.9K — a different platform, not this one.

Red Faction

In Red Faction, you play Parker, a weary miner who works for the corrupt Ultor Corporation. You reside on Mars, sometime in the future, and when a plague spreads through the mining community, some of the Ultor employees uncover a massive conspiracy. Thus ensues a battle by a group of lowly workers, headed up by the educated Parker, to expose the deadly experiments Ultor has unleashed onto its work force. Red Faction was a very big leap forward in the FPS genre. It introduced many new technical features such as location-based damage system, real-time skeletal deformation, advanced physics simulation, destructible environment and more. The unprecedented (at the time) interaction with the environment creates a very strong feeling of immersion that is very impressive even by today's standards. Unique set of features such as location-based damage system, real-time skeletal deformation, advanced physics simulation, and destructible environment. An ability to use land, sea, and air vehicles during your missions. Compelling storyline (written by the creators of the famous FreeSpace series) that will keep you hooked for many hours.
