Starfield can be compared to SQ42 (which most likely, Starfield I mean, will have an edge on SQ42 in terms of story/quests/characters), modability, etc. SQ42 should have been launched for a while now if they would have bother to get at least something out (but that would have change the income stream for SC if the single player was far for perfection - and most like will).
Testing hardware for this, I suppose, it can be useful for the people that actually play it for a relative long time and constantly, but when you take into consideration that is an ongoing development can be a bit pointless. In 5-10 years from now there's a lot that can happen.
Its single player, yeah, but its likely more open world than SQ42 which is an on rails story driven campaign, its the main aspect of Star Citizen lore as a stand alone game.
Starfield is... well Skyrim in space.
That is the only thing that makes me feel a bit like those ED Odyssey refugees did, Bethesda games are usually made multiplayer by the community but i think they will struggle with this one, there is a reason why games on this scale, NMS, ED Odyssey... are not MP, at least not in the proper sense, and Fallout 4 is about the size of New Babbage, just one city on one planet on that one Star System, it is also just a piece of land.
Its that Multiplayer aspect, on a literal universe scale, with no level loading, because you can't have level loading in a multiplayer game, unless you nail everyone to a chair which wouldn't work in Star Citizen because you have ships with an interior that is full of your crew mates running round in there all doing their own thing. people are flying 890J's around with 100 people on board ####'ing about.
Its why this aspect of Star Citizen is unique.
While this seems like such a simple thing but its that limitless experience that makes it what it is, there is no "you can't do that" orbit drop a crewed APC out of the back of a cargo hauler, because why not? Oh ok... that's a global physics grid containing a planetary physics grid supporting on movable physics grid which its self is supporting a movable physics grid containing 6 people that is then moved out of the first movable physics grid into the planetary physics grid... and the code is just supposed to go "oh... oh ok so this is happening, i'm not going to freak out"
I remember the early days before they perfected it, hilarious...
This is why David Braben (Elite Dangerous) after first promising ship interiors for the Odyssey expansion had to back track and say "yeah about that, sorry, not happening" not because "its boring" we all know its not that, ED level loads everywhere, that planetary entry effect, its a loadscreen, no EVA, no parking whatever the #### you like in any random ship if it fits and if it doesn't use force and maybe lose some extremities to make it fit.
It took about $100 Million and a couple hundred of the brightest people a few years to achieve it, other studios with ambitions to emulate it have thrown in the towel. So i don't have a lot of confidence the Bethesda fan community can pull off what Bethesda, Fronter...... couldn't, the best thing about a vast limitless "no" to nothing sandbox is that the tools and the environment exists to sandbox whatever you want, and that is best experienced with your friends.
I am looking forward to Starfield, but i know what to expect.
