Wich are right rules for Warp Navigation?

Either.

You could argue that the Navis Primer one is the right one as it is newer, but you could also argue that the Core is the one since Navis Primer is an addon book, so to speak.

Play by the one that makes the most sense to you (or your GM). It really is that simple.

Indeed. The Navis Primer rules are meant to replace the Core rules. Not to mention mess up existing characters and previously published supplements.

A sidebar or something acknowledging and explaining the significant changes made would have been nice.

I'm actually fairly unhappy with the Navis Primer rules - the primary issue being how they translate on journeys of even average length. If you have a 180 day journey (easily doable), you are rolling something like 36 times on the warp events table. Statistically, something like 7 of those will be "all clear" while the other 29 (on average) are *something.*

Sure, your Navigator can avoid many of those with rolls, but the level of dice rolling quickly becomes unmanageable. That's not even mentioning the fact that you can wind up with a campaign that goes a bit like this:

1) Start of adventure - do stuff!

2) Oh noes! We must go to System ZOMGFARAWAY! for the next step!

3-25) Warp encounters!

26) What was the adventure again?

God forbid you have that Miroslav drive (I think?) where it's a check every 3 days… Then you have 60 rolls on the Warp table…

I ended up houseruling it in my campaign - I'm sticking with the warp travel durations from Navis, but I'm going to just use narrative stuff for most of the warp encounters. My players' eyes started to glaze over when I busted out the Navis rules, and I'd rather they have fun than stick with RAW.

(The Miloslav warp engine reduces the duration of all warp passages by half. So in your example the trip is 180/2=90 days. You roll every three days. 90/3=30. In other words, in return for getting there in half the time, the journey becomes safer . Also, the Miloslav requires less Power and does not cost anything extra.)

You use the Navis Primer for when you want Warp travel to become an adventure in itself (you even earn Profit Factor from it). If all you want is for your group to reach the destination so they can get on with their plans, stick to the core rules. After I started using the Navis Primer, the group is far more careful before venturing into the Warp, and they respect it to a much larger degree.

Also, if you're stuck 180 days in the Warp, your navigator sucks.

I may be plaing a Navigator in an upcoming campaign, so I have the same question.

Also considering that you have to make at least 3 rolls per Encounter (one to check if the Navigator sees the encounter; one if he can avoid it and one to steer arround): If you have a longer Warp Travel, doesn't that lead to an aweful lot ol dice rolling form the Navigator while the other player are more or less bored?

IMHO, Navigators are best suited to being NPCs as they have many of the Shadowrun Decker issues and then even more from being mutants. Sure, they're house mutants, but mutants nonetheless.

If you don't want to use Navis Primer as whole, I'd still recommend using Psyniscience for "Locating of the Astronomican".

1.All Navigators have psyniscience pre-purchased, Awareness has to be purchased.

2. Naviscions can't even purchase awareness. Good luck navigating anywhere!

3. Astronomican is a psychic beacon on Terra, how mundane Awareness is better for tracking it than Psyniscience?
