Don't conflate the homogenization present in other games with artistic intent and motivated use of color in another game.
This doesn't look like "Generic Space Marine Shooter with Drab Colors #2054." There are enough videos and screenshots out there to show that The Order isn't just a brown game. It's establishing a specific time period and tone. It makes sense for 1886 era London to look gray and muted when it's foggy and wet out. Limiting the colors in the environment paints a specific atmosphere, and makes the
blue of the arc gun or the
orange of an explosion stand out even more. Other scenes show a subtle blue at dusk/night, bright orange at dawn, indoor areas with varied colors due to the fabrics and materials used, etc. It is, *shock*, a very cinematographic, film-like approach to the use of color.
Writing The Order off as yet another bland looking game based on one set of screenshots of a singular area/sequence of the game seems like unfair nitpicking, especially when all evidence points to the game being one of the more carefully considered from a visual perspective we've seen in recent memory. You can just not like how it looks, but bringing up the homogenization of the lazy and unimaginative use of color in games doesn't seem to apply to this specific game.
