Although not often done, game campaigns in our world can have multiple levels too. Think about the idea of running a campaign based on something like Inception. There are various "dream" levels through which the PCs can move, and at each level reality is somehow different, yet their actions there affect what happens on other levels.
If you think about it in this way, a slightly simplified version could be a cyberpunk game, in which the alternate reality of cyberspace provides a distinct "level of reality" that the players can interact with as though it were another world. To break into a secure data facility and steal information, you can either infiltrate it physically, or you can jack your brain into cyberspace, and navigate a virtual world to find and download the data there, breaking through cryptographic security and electronic guards that might fry your brain rather than shoot you full of bullets. Or for a different style, consider The Matrix.
When you think about alternate realities in this way, there are many more examples you can come up with. Games with a supernatural element can use a Dream World - think A Nightmare on Elm Street, or the Dreamlands of H. P. Lovecraft. Entering the rabbit hole into faerie realms can provide a similar effect. Technology can simulate this too: Captain Jean Luc Picard in the episode "The Inner Light".
You can throw another level of reality into almost any genre of game. Think about it for a bit and see what other ideas you can come up with.
[Reminder: Our guest commentators have not seen Rogue One. Part of the fun is seeing how their untainted impressions re-interpret the movie through the lens of our comic.]
Wait wait wait.
The Rebellion does know about Princess' heritage right? At least high-ranking members like Mon Mothma? She was there when everything went down, and obviously Bail knows. But he's acting like it's a secret Mon Mothma wouldn't know about.
Perhaps it's just Jim himself forgetting who knows what, and obviously Princess didn't know at this point, but if this wasn't a known secret the Rebellion would be wanting to protect, why would they be trying so hard to protect Polis Massa?
Hmm...

"My daughter knows the place like she was born there". Absolutely truthful. Although since this takes place before campaign four, his daughter should be an NPC.
Now, why do they want to thwart the Empire from learning anything from Padmé's birthing facility?
Rechecking the comics, the idea is to scan systems near Kamino to try to find a water planet. Additionally, the whole idea of "if we have access to the secret database, we can use the information in it as well as the current information about Kamino to locate Toprawa" does nothing to make Kamino relevant given that Toprawa/the secret database is hidden, so there is no reason to think that the Empire will have any interest in the birthing facility, or anything there (other than a cloning facility actually).
This highlights the problem of a rebellion or other underground resistance - if you make too many attacks, you'll wind up hitting a well defended place by accident for no good reason when they weren't expecting you, had no reason to expect you, and you had no reason to be there in the first place.
Because you just know that the mere fact that they are sending a force to this base means that there will be a large contingent of Empire forces there. Even if there wasn't a large contingent of forces there yesterday.
Hold on a moment. Leia/Princess is going to the base. And Bail Organa is going to be one of Jim's characters that dies. And Leia is going to wind up on the diplomatic ship.
How will they manage to get Leia off of the base, onto a ship, have that ship receive a transmission of the Peace Moon plans, etc. - the transition from Rogue One to Campaign Four seems really contrived.

Jim: {present day} And while I was flying to Kamino, I was also planning the mission to Polis Massa.
Pete: As Bail Organa, he means.
Ben: Right. Because keeping all the different levels of this campaign straight wasn't confusing enough.
Mon Mothma: Like, oh em gee, Cassian's squad has gone to Kamino. But what about Wedge's intel on Polis Massa?
Bail Organa: So here's the plan. Our goal is to thwart the Empire learning anything from Padmé's birthing facility.
Bail Organa: We take a suitably sized fleet equipped with standard complements of weapons, troops, and droids.
Bail Organa: I'll take my daughter with me. She knows the place like she was born there.
Bail Organa: We'll cautiously scout the system, appraise the situation, and commit forces as appropriate to our objective.
Mon Mothma: Wow, Bail. Your plan, it sounds, like, so so sensible.
Bail Organa: Yeah, I've got doubts about it too, but I'm gonna run with it, because I'm roleplaying.
