Games that support 21:9, and that would look awesome on my new monitor !
1.Kingdom: Classic (2015)
The whole concept for Kingdom is that of a horizontal scroll "RTS". Playing this on a widescreen monitor i must say is very handy and adds to the immersion. Galloping left to right and back in this gorgeous landscape is fantastic.
2.They Are Billions (2019)
See infected coming in from far away!
3.Cities: Skylines (2015)
4.The Witcher 3: Wild Hunt (2015)
5.Trine 2: Complete Story (2013)
trine's visual is one of the aspects that make it really standout, the more the environment shows the happier i am :)
6.Metro Redux (2014)
more immersion for an immersive game
