I know Elite is dropping Mac because of this. Wouldn't be suprised if a lot of other games have/are too. Apple is crazy stupid with this and just screwing over their own users.OpenGL is deprecated in 10.14 Mojave. /eyetwitch pic.twitter.com/rUHyZamaPF

Goody goody gumdrops.
To clarify, all the OpenGL based games won't break immediately when Apple releases this update, but it is official confirmation that when they do, they aren't going to fix it. Additionally, they're supporting exclusively Metal, which means that developers are either going to have to extensively re-write their games, try to get MoltenVK to work with a Vulkan build, or (most likely outcome) not bother with Macs at all.
