well I’d say no f******** way b/c it sounds huge. If you scoped it down to something that a small team could make, then maybe. I guess the plan seems crazy big. How can you offer all those choices w/o a lot of background work? It just seems like something a team of 40 would be hard pressed to make. If you said Take 3rd person shooter add enemies and dialogue system that makes changes based on choices… maybe but even thats pretty big.
So how do you think you could make something like that? Modding is not the same thing
