Wait, which RPG models velocity?

The HERO system can do this! Just spend the next 6.5 hours coming up with the correct model to use for your calculations and not only can you accurately model velocity but you'll also be able to determine exactly when your players completely lost interest and wandered off to do something else.

Wouldn't the moon have a massive penalty to its Hide checks due to its size?

I wanted to write up a fake DEATH BATTLE write up for when two PCs in the campaign I'm in were facing off in a tournament battle and tried to do that style of math, "Well if with base 40 feet of movement, with Haste, Bonus Action Dash, +5 from this, +10 from that... They can move at the SPEED OF SOUND!" but I didn't have their sheet so gave up at trying to figure that out. It was fun writing up what I could, reviewing my session notes to track their achievements: "These two Heroes have been friends and adventurers, saving the world one Irate Dragon at a time, but who would win if they had to turn their weapons, skills and abilities on each other!? This is Thundertwig and I'm Sorc, and it's time for a FINAL FIGHT!!!"

Doesn't Cyberpunk or Shadowrun do something like it for modeling grenades exploding in a small enclosed space?
Yeah, Cyberpunk 2020 grenades rules for:
_where they land (you roll)
_how they scatter (a table)
_ and depending on the blast radius a frag has, there are optional rules on how to distribute damage on a group in its blast radius (probably what you are talking about). And yes it includes walls and enclosures.

I can also think of at least one OSR game with bouncing/missing rules for grenade launchers. It's like you missed the target AC? Roll 1d12 for the direction and 1d6 for the bouncing range in meters. Now hurt everyone in blast radius.

Back in the Murphey's Rules thread, yes. Offsite version available here.

quote:

Except, well... the problem with line of sight is that checks made to Spot something take a -1 penalty per 10 feet of distance. Given that our moon is somewhere around 1.2 to 1.3 billion feet away, you're looking at a 120 million penalty to your check.

But wait, the moon is pretty big. Things take a penalty to their checks to hide based on how big they are. The Tarrasque, as a 50 foot tall killing machine, takes a -16 penalty to its checks to hide (and thus is incredibly difficult for your average commoner to spot if it's standing on the other end of a football field). The epic rules have options for creatures larger than colossal, which basically dictate that every time its size doubles, it moves up another category. 64 feet (2^6) is the bottom for Colossal, providing a (-8) 2^3 size penalty. The moon is 2159 miles wide, roughly 11.4 million feet. 8.3 million feet is around 2^23, which means the moon is somewhere around Colossal+17, and takes a 2^20 size penalty, multiplied by 4 to offset your spot check (2^22, or roughly 4 million).

You take a -120 million penalty to spot the moon, offset by a 4 million bonus because the moon is big. Unless I screwed up by a factor of 64, you probably can't see the moon.

The sun is roughly 400 times larger, but also roughly 400 times farther away, so no luck there. Other stars may range from the sun's size to 1500 times larger, but they're also 250,000 times farther away at minimum.

The skies above Greyhawk are black and empty. None have ever seen the stars.

I- I don't even know what you just called me!
Shadowrun has the "Chunky Salsa" rule, where if the blast of the grenade hits something that it doesn't blow up the shockwave goes back, which hits the character again. This can make a 5 foot hallway become you getting hit 6 times the damage of the grenade.

This is the point where, as the DM, you turn to the offending player, mutter something along the lines of "Congratulations. The moon, as an inanimate object, is not trying to Hide. You successfully Spot it." and threaten to start throwing erasers at them if they bring it up again.

3.5 Rules on the Spot Skill posted:

The Spot skill is used primarily to detect characters or creatures who are hiding. Typically, your Spot check is opposed by the Hide check of the creature trying not to be seen. Sometimes a creature isn’t intentionally hiding but is still difficult to see, so a successful Spot check is necessary to notice it.
The target not intentionally hiding is not sufficient to automatically succeed a Spot check. You can rule circumstance as the DM since there is a "sometimes" in there, but "it's not hiding so you see it" isn't an automatic property of how Spot works.

Surely the sun should be giving you a spot penalty from the glare. :v:

(though posts, like celestial bodies, presumably aren't characters or creatures anyway so maybe those rules are irrelevant?)

Much more relevant is how utterly inflexible 3.5/Pathfinder is at letting characters try any physical action that isn't specifically baked into their character class. Want to surprise swing a chandelier into the dastardly villain and knock him down with your momentum? Unless you specifically took the Dashing Rogue prestige class or the Attack from Swinging Ceiling-Mounted Object feat, it's gonna be strictly worse than just walking at a brisk pace towards the villain and calmly attacking him. Want to swim underwater at night, grab the dozing dock guard by their ankle and drag them into the water? The grapple rules forbid that in eighteen different ways.

This is one of the things I most dislike about 3.0+ style of play, at least the groups I've been in. People treat their character sheet like a menu in a video game. If it's not on the menu, it can't be done.

"... IS THE MOON A GOD drat CREATURE? You know what, gently caress it. Give me one second..."

*rolls dice*

"Were you actively hiding? No? Roll initiative, the ELDRITCH HORROR that was the moon has awoken and it sees you. Congratulations, you fail to go first, and the moon eats you."- Me if I was DMing and people started saying that during the game.

I mean, it's funny, but your own highlighted quote does specify creature, not "creature or object". Which means characters will always find the TV remote, unlike me.

You don't need a skill check to navigate to a place you can see if there is no obstruction that breaks line of sight.

The Spot skill is used primarily to detect characters or creatures who are hiding. Typically, your Spot check is opposed by the Hide check of the creature trying not to be seen. Sometimes a creature isn’t intentionally hiding but is still difficult to see, so a successful Spot check is necessary to notice it.

A Spot check result higher than 20 generally lets you become aware of an invisible creature near you, though you can’t actually see it.

Spot is also used to detect someone in disguise, and to read lips when you can’t hear or understand what someone is saying.

Spot checks may be called for to determine the distance at which an encounter begins. A penalty applies on such checks, depending on the distance between the two individuals or groups, and an additional penalty may apply if the character making the Spot check is distracted (not concentrating on being observant).

Nowhere in this description does it imply that you would need a Spot check to locate the moon, so it doesn't matter. You don't have to roll for everything. The moon is not difficult to see.

I find these jokes puzzling. You can't fault a dungeon crawling tabletop game system for failing at modeling celestial objects, or any kind of physics phenomenon that isn't relevant to "four guys fight at most a dozen other creatures in close-range combat".

D&D 3e presents itself as a rules system to model a simulated world and everything in it - in fact these jokes can only work because D&D makes that claim, and is not very good at it. "spot the moon" is a more absurd version of your "rock'em-sock'em-robot full attacks are better than improvised attacks", the result of sedentary game designers throwing together rules and numbers based on what "makes sense" without thinking about the result. it's the same as Burlew making fun of 4e for having a max weapon range of 150ft, save 4e was more honest about being a tactical squad combat game

I don't think D&D 3e has ever made that claim. The joke works on some level because lots of rules get added in to adjudicate real world scenarios like that and supplements add systems and subsystems that lends to that feeling but I don't think its ever been officially been the case. Maybe some players/DMs act this way, but that isn't really how it works.

ok, maybe it doesn't want to model everything. but you can compare D&D 3e and similar games, where rules approximate real-world physical processes, to games like Apocalypse World etc., where rules approximate narrative processes
