Many gamers have setups with two or monitors. Oftentimes these differ in size, resolution, even aspect ratio. They can be very helpful in productivity tasks, but mid-gameplay they rarely serve as more than displays for external music or chat.
Are there games that utilize this extra space in a unique way and are played better or exclusively with two or more monitors? Preferably something more than just extra FOV
Back in the day Supreme Commander could utilize a second monitor for a dedicated map that you could zoom in and out of independently of the main game window. I don't remember if you could do other things with it, but I thought it was pretty sweet with just that.
Simulators, like x-plane or flightsim, and I think some driving sims can use lots of monitors. Like 4 monitors for the cockpit windows and another two for control panels etc. though you need a hench pc and graphics set up to do this at a decent frame rate
Probably not quite what you meant but two monitors for Dwarf Fortress is a god send. Game on one screen, the other for DFHack console, Announcements, SoundSense, Dward Therapist, and various other utils. Could probably use 3 actually...
There was a 3D military tactic game or two from one dev that had dual monitor support. Where the second monitor became an overhead map that let you issues commands.
I've heard rumours that Kitten Space Agency (the spiritual successor to Kerbal Space Program, considering KSP2 is dead on arrival) will support multiple monitors.
I know it has multiplayer baked in at every step of the development (even if it won't be available on release). So maybe I'm getting my wires crossed between multimonitor and features of the multiplayer that sound like they would be great for multi monitor (IE, someone plays as ground control)
Dariusburst Chronicle Saviours on Steam. Maybe the PS4 variant has some magic for multipule monitors, too but I'm too lazy to look. There may also be other Darius ports that utilize multiple monitors but this is the main one in the series.
It's a horizontal shmup that used large displays in the arcade cabinets, that may have been multiple monitors but my memory is fuzzy.
You can stretch the game across multiple monitors in the game settings to replicate the super wide feel of the arcade game. They even have some "cabinet" connection options in the port that let's you compare your scores and see replays from other players.
while not a novel thing such as extra menus or something, it let's you play the game closer to its original format.
