Rations come in portions of "one week" when you buy them, which I assume is meant for "7 days". But their encumbrance is listed as 4. There are rules for penalties for not eating, which are based on days. So what happens to encumbrance when you eat one day's ration?
Rations feels like it ought to be one of those bundled things, but it’s not. I think we’re going to treat them as either all there or not for simplicity’s sake. Otherwise, the easiest thing to do is reduce the encumbrance by 1 for every 2 rations consumed.
Travel speeds are given in miles per hour, but depending on terrain it might 1.5 or 0.5 miles per hour. The game also recommends using 6 mile hexes. It would be vastly more convenient if travel speeds would be given as hexes per day. Encumbrance doesn't impact travel speed at all. But I do notice with appreciation that mounts with faster movement rates don't make overland travel faster, since they can't be sprinting the entire day.
This feels like another place where WWN is too verbose for its own good. If it just did what OSE/BX does, it would be easy. PCs generally travel for ten hours per day, and the distance traveled is their movement rate in miles. If you want hexes, divide by five. The terrain type table should just be a list of modifiers.
Speaking of which, road travel seems a bit too good. 2× is almost (but not quite) taking the run action every round for ten hours straight. I’d expect PCs to be very fatigued jogging for ten hours straight. The Alexandrian’s
method is too fiddly, but I think having separate on-/off-road speeds is the way to go. I may tweak it for my game.
WWN also has nothing to say about getting lost. I assume it’s a “don’t make the PCs look incompetent at their role in life” thing, but one should expect there to be situations (like
arratu wastelands) where success isn’t a sure thing. It’s not difficult to devise a DC, but still.
