Yeah I signed the form. I will likely get it if it is sold on Linux. Not sure how the gameplay is, I thought it was meant to be like Total Annihilation?
When it comes to DX12/Metal/Vulkan, the polishing is mostly up to the game developer and vendor drivers. I hope RADV catches up fast for linux soon, or AMD opens their version of Vulkan. RADV atm only just keeps up with OGL but never surpasses it.
