Rogue One is the rogue one. http://makingstarwars.net/2016/08/gareth-edwards-discusses-the-meaning-of-rogue-one/
Let me guess, Anakin made him first, and Dark 2 D2 smashed all the other projects Anakin was working on before fleeing. R2 has to go find an old 3PO unit living on a desert planet to get information on how to stop Dark 2 D2, unfortunately, the 3PO unit is killed before he can complete reprogramming R2. Then, in the sequel, R2 finds an old mousebot that shows him how to defeat Dark 2 D2.
International posters. Meh, they're okay, but I want the one in the classic Star Wars style like the other 7. C'mon, Disney, hurry up! Chop chop!

I like the poster, but I wish they'd drop the A Star Wars Story and just call it Star Wars Rogue One like they did with Clone Wars and Rebels.
