I don't think it's gonna differ that much from the ES and FO BGS-style of RPG.
Yeah, the ground part. But I still have no idea how "space" is gonna be part of the gameplay.
Are planets going to be just separate quest hubs? Is flying in space going to be just a "loading" thing or a seamleass part of the exploration?
Will we get seamless planetary landing like in Start Citizen or a cutscene "Yeah, you totally landed there"?
Are we getting one default space ship? Or several possible space ships? Are we going to able to pilot them manually or will they be a "fast travel gate" and call it a day?
Etc, etc, etc.
