Some people, I'm sure, will use the Sentinel Comics RPG to make their own super-worlds. But others, I'm sure, want to run in the Sentinels universe. Obviously, we don't know the full scope of what will be different in the post OblivAeon universe, but, based on the Letters Page, we know a few things.
How closely are y'all planning on sticking to the canon?
For instance, they've said that the walls between universes are closed and that time travel is impossible. I confess I'm a fan of both of those things, so I'm thinking that, in my slice of the Multiverse, instead of being impossible, it's just really really hard. Because I want to do a Mirror Universe adventure or two, and I love Evil Dopplegangers from alternate dimensions.
As for Time Travel, part of me wants to do something like River Song in Dr Who, where the PCs might interact with La Captain from "before" OblivAeon. Or possibly steal from the CW, and have there be some kind of "time remnant" of La Capitan who somehow managed to escape, and is sailing madly through time trying to find some way to escape her destiny. I had this image of La Capitain and her crew, looking ragged and desperate, fighting like mad to get through the PCs to some McGuffin, and one of the crew just randomly pops out of existence, because time caught up with that one.
