as someone who never looked into the game heavily, I just knew about it. it was very informative. I do not think GMOD needs replaced. I think there just isnt anything like gmod using a modern game engine. and I think that would be nice! plsu maybe it could replace it depending on how it works out. If its better, then its better. But if not thats okay they can obv both be their own thing.
Really good, probably the best introduction vid to people who don't know what S&box is. Only sad he didn't say a Sandbox game is in the works while being sad that the game currently doesn't have (an official) one.
