is it beyond facebook's capability? no. Is it beyond their will? Yes. I was once naive, I joined Google to make a game engine. My belief at the time was like yours. It's Google, they're a giant company with infinite resources. There's no way this won't take over the game engine world. it wasn't until about 14 months in I realized that competing with Unreal and Unity wasn't just a mater of 30 people building an engine. to actually succeed it would take more like 300-400 people and a mandate for those people to form an everlasting division within the company of support. people to make an IDE, people to continually update the engine and IDE, people to hand hold devs. people to make 100s of videos. people to run classes. people to organize conferences. people to organize game jams. people to do bizdev. people to woo the top devs. people in all the major game dev hubs in the world, people to localize docs, etc... this works for unity and unreal because selling their game engine and services is their core mission. for Google (and for Facebook) all it would ever be is some open source code of some under featured engine they ship once and forget. Unity has about 1000 employees. Unreal has at least 250. Their entire missions are to make, sell, and promote those game engines. That will never be facebook's mission which is why it would never succeed.
