How much M.D.C. does a planet have?

Well, the Robotech mega weapons wil do upto 4D6x1 Million MDC and only leave a sizable crater.

Extrapolate from that.

You do realize that when it says "Demon Planet" it means planet controlled by demons, and not planet-sized demons?

Theres a good chance that I just insulted you, which was not my intent, so if I did please let me apologize right now.

To blow a planet to bits like in .... you would need to not only inflict billions upon billions of MD but defeat the gravity created by the mass of the planet. Evectivly destroying all matter on the planet through atomic reactions. I would suggest if you are going to do this (create a planet destroying weapon) just say it works by breaking down molecular bonds and dont offer a damage total. If you are trying to make a planet uninhabitable i would say a synchro-cannon would do the trick. I suspect 4d6x1 million is enough to burn through the crust of a planet effectivly creating a super volcano poisoning the atmosphere and killing all but the smalest of life on the planet in a matter of days or weeks.

Wrong. Check out Three Galaxies. There are "Demon Planets" that are actually planet-sized Alien Intelligences.

However, the Synchro cannon descripion lists a crater depth (which I admit is not near me) of a few hundred metrs or less. The crust is a few kilometers thick.

Besides, the Earth got bombarded with thousands of Synchro cannon blasts in the RT series and more than 30% of the population srvived.

For a Terran style world?
Think into the multiple billions of MDC.
For a Jovian sized world?
Think more.
Again -sigh- (how many times do I have to reapeat this) it's a moot point.
It's GM's call on how much damage is required to blow the world up. Here's another thing to think about though; one doesn't need to hammer the rock till it crumbles...all you need to do is find a fault line and apply JUST enough damage to that point to cause catastrophic stresses.

So reapeat after me; "The GM is final arbitrater of all rulings...PERIOD"

Just say: "the planet explodes into chunks which fly out into space", and be done with it.

Avoid the math.

IMHO that doesn't do a synchrocannon justice. I figure if you fire it at a fault line and mantain the beam for more than a few seconds it will burn through. After all we are not talking about an explosion here it is a beam weapon wich vaporizes all matter in its path of fire. The damage values are there for the munchies who will undoubtidly use it to kill planets as a solution to all their problems. :shock:

Considering that the diameter of the Earth is only 7,926 miles, the smallest Demon Planet is around two and a half times larger than the Earth. If we take that at face value (as opposed to just an ill considered number randomly thrown into the book) , an Earth-sized planet should have around 2,000,000 MDC.

Nope the numbers were not random. They were very carefully calculated using data provided to me from Nasa along with my own research. They had to be big enough to munch on an earth sized planet. :mrgreen:

I would suggest the Low MD value for the deamon planets relates to the fact they are living things capable of sustaining only so much damage before dying. As for their size Carl did his research so that is that. Imagine a dead demon planet Ewww!

Mmmm. Globalicious.

Darkmax, what's up with the name change? Are you Darkness or Darkmax 2?

I changed the damn username and now I can't get in, it seems the password's also changed, and so has the damn email.... I simply cannot login.

In space, no one can smell you rot.

Actually a planet sized being which consumes other planets will rot because it will be carrying all sorts of alien bacteria.

how did we get to discussing 'movies' .. and 'toys' .. on a thread that asked a question? ... the question was '' how much MDC does a planet have?''

good question. personally i would assume that the MDC of a planet would be more than 'one shot causes it to explode into millions of glittery pieces' ... THAT sorta stuff is 'totally hollywood' ..

i would think .. that considering the size of the planet that you would do a 'continemtal landmass*square miles x circumference in miles x 100 GDC per square foot ' to get a base idea of what the POSSIBLE amount of MDC a planet has ... and you will STILL be at a loss

1 GMC = 1000 MDC .. so you have a clue of what i'm talking about ... think giga damage .. i believe that was the word ONE person had called it. and i think it wa 1000 MDC .. it might have been 100 MDC ... but you get my point ... right? ... one planet would have MDC into the TRILLIONS of points

so .. lets stop with the 'lets gloss over the subject cause it will make me have to think' answers, and actually TRY to think of how may points it could have? ... sure, attomic bombs did massive amounts of damage .. but it was minimal when you compare it to he shock waves that followed that flattened the area. then you deal with radiatiion .. but hey ... look at what the earth does after that? ... it heals itself ... sure there will be 'mutations' .. but its the planets way of HEALING and RECOVERING.

so .. nuff said? ... this time ... i hope?

This board in particular seems quite prone to having the various threads go on tangents shiiv-a. I don't think anyone was intentionally trying to "gloss" over the question.

I think the Demon Planet is a good reference. A planet would probably have more M.D.C. probably because it would be a lot denser than a demon planet.

From a writing point of view it would be difficult to assign a single weapon with a value to destroy a planet. I would just say its capable of doing it period. Remember the dice value for damage is meant to keep track of things like hit points, S.D.C. and M.D.C. For a planet you're either going to destroy it, make it uninhabitable, or vaporize a city or two. Which is why I say don't bother coming up with a M.D. value.

agreed. at most, you'd put down "can blow up an earth sized planet", and let the game master decide how it effects worlds larger, smaller, ect.

the only thing you'd need to stat is the vehicle carrying it, so your intrepid band of hero's can destroy the weapon.

kinda like how you don't need to know how much energy the death star's super laser can put out, but you do need to know that the thermal exhaust port is ray shielded, and you need to use proton torpedo's.

Besides it is almost impossible to tell how much MDC a planet should possess.

1. Each planet is of different size.

2. Each planet is composed of different and varying elements.

3. How thick is the crust, if any, does that planet have?

you can';t just assign one set of stats to cover it all.

Agreed. Take a look at a planet like saturn. Earth actually has more density despite how big saturn is. Also if I remember correctly saturn would float on water if their we a huge sea.

How much damage does the super laser do in that space movie? (Trying to dance around the conversion rules!) Enough to destroy a planet!
