simplifying parachronics in Infinite Worlds

[Lurconis]

I'm running an infinite worlds game for a group unfamiliar with the setting, and I've run into a spot of trouble - namely, when I try to explain things like "Quantum Levels" and the difference between conveyors and projectors, their eyes glaze over and they say something to the tune of "This is time we could spend punching Nazis instead of learning about imaginary physics!".

I had a bit of a think about it, and decided it might be just easier to massively simplify the way parachronics works in my game. Here's the explanation I gave them:

"A parachronic projector functions basically like a stargate that doesn't need to connect to a destination stargate. You dial in the co-ordinates for the world you want to travel to, and you step through a portal to the exact geographical point on that world that your projector occupies on your world.

Very few alternates have the physical laws that allow for parachronic travel. As such, projectors do not function on the vast majority of worlds (hence why so few advanced worlds ever develop the technology for travelling between dimensions), but projectors can create portals to these worlds easily enough. As a result of this, travelling from one world to another usually consists of a) waiting for a scheduled portal to be opened, b) stepping through to emerge at a projector on Homeline (or another world that projectors work on), then c)using the projector to open a portal to your destination.

Also, some worlds are "farther away" than other worlds, and cannot be directly traveled to; to get to one you would need to find a world that can travel to both (and that has projectors work on it). For example, it is not possible to reach Centrum from Homeline, and vice versa - so far, encounters between them has only been on worlds that both can travel to."

Now, obviously I've changed the way it works quite a lot - there aren't any conveyors, characters on the vast majority of worlds have to travel through a stopover world where projectors operate, projectors work by making a portal and "Quantum Levels" have been dropped. But I think the changes make it a little easier for a new player to understand, and don't really change the feel of the setting that much.

Are there any potential problems anyone can forsee with doing it this way?
