How many such game development companies actually are there? I see a lot of aging engines out there, and companies that jumped to unreal, but I have by no means broad knowledge
Gaming companies get a lot of crap for this - it seems unfair. The OS I'm using to write this is a relative newcomer at only 30 years old. Obviously, it has changed a lot in that time, but so have the engines. Most software doesn't get rewritten, it evolves.
