Been thinking of a game idea set just prior to ANH.
I recall reading of a scene from the Tarkin novel about an installation attacked by Separatist forces.
By that I mean they used Clone Wars era warship and fighters but we're driven off.
My idea starts off with a group of characters who are being covertly inserted aboard the Death Star, they're present when Tarkin blows up Alderaan and wanted to see how a group would handle that and trying to stay hidden.
I'm thinking about revealing Erso's message reached them and throwing in a flashback revealing they started off on Scarif narrowly avoiding the resulting rebel fight having carried a copy of the Death Star plans as the Rogue One team had landed they left offworld narrowly missing the resulting fight.
Using the plans they've been modifying the weakness by establishing a transmitter to guide a missile down the shaft to cause the destruction of the Death Star.
Part of my adventure idea involves them encountering Obi Wan Kenobi making sure to tell him of their modification but assume when Vader killed him this failed.
That's why he got Luke to shut off the targeting computer as Obi-Wan was able to pass on the details resulting in Luke's "miraculous" shot and the destruction of the Death Star.
What do you think?
Too railroads?
