FOSS CAD softwares. I know FreeCAD exists but it’s very unintuitive compared to the proprietary ones. I am thankful that it exists but it’s a long way apart to become a household name like Blender.
I wish I could start writing one but I don’t have a clear picture of requirements to plan and start writing one. If anyone is expert in this field please link some research papers and guidelines for someone to start fresh.
I’m not sure about Forza, but check out This guy. He makes out great engine simulation sounds that are close to real life counter parts
