Galaxy progresses in real time. There’s no do-overs.
Now in terms of what you’re suggesting, how exactly would it work? Key points:
- it has to happen as it happened
- many things were as a result of the compound effort of lots of people so how do you recreate that?
- further to the above, which person’s role in things would you have the people take?
As an absolute rule for this stuff, you can’t do it in a way that will give people false expectations of how they will fit in to the real ED universe.
People can’t take the role of the person who did it all, because typically there wasn’t one person.
People can’t be the hero or villain, because generally speaking, there was no hero and no villain.
How are you going to account for things which only happened because of people using their brains, and/or mass efforts?
The (in-game) tech used would have to be the same as was used at the time, which is going to cause issues and confusion.
And so on and so forth.
So how would you propose it actually all works?
Don’t take all that the wrong way OP, but story mode, quest lines, etc. have been suggested many times and almost always never take into account all the stuff that would need to be taken into account. If you’ve got any well thought through ideas on how to approach it, then I’m sure they’d be well received.
(Way back when, a suggestion I made was for a standard cinematic intro to the ED universe (giving a very brief history of things since the present day) on first start of the game, and then supplemental more detailed ones which the player could watch at their own choice. We kinda got a bit of the latter in the Codex, but I'm not sure how much new players would look at that stuff (or existing players for that matter) and still reckon we could do with an 'intro to the ED universe' cinematic or equivalent.)
