I’m looking at star citizen and how long their engine and tooling process has been. It can be quite significant.If you want to make a game that is like the Uncharted of Star Wars, you're up against Probably 11+ years of tools that Naughty Dog created for the Uncharted series. I honestly don't know how long it would take to fill the gaps in Frostbite to make a cinematic 3rd-person adventure game, but I imagine EA just wasn't willing to wait for as long as it was taking.
