Planet Creation Tables

Planet Creation Tables

The Universe is pretty damn random, so the different kinds of planets that you can run across is innumerable. This might or might not be a complete list of the best possibilities I could come up with, and any suggestions or ideas will be appreciated.

STEP 1: PLANET SIZE

01-25 Small: Equal to Mercury or Pluto
26-75 Medium: Equal to Terra, Mars, or Venus
76-95 Large: Equal to Neptune or Uranus (No jokes please)
96-00 Giant: Typically a Gas Planet, equal to Saturn or even Jupiter.

STEP 2: PLANETARY SATELLITES

Roll once on this table for Small & Medium planets, roll twice for Large & Giant planets (ignoring a roll of 81-90 on the second roll).
01-15 None
16-30 1 satellite/moon.
31-65 Few satellites (roll 1d4 for #)
66-80 Several (roll 1d4+3 for #)
81-90 Many (roll 2d6+4 for #)
91-00 Debris Ring (roll a 1d6, 1-4 thin debris ring, 5-6 dense debris ring)

STEP 3: LENGTH OF THE PLANETARY DAY

This depends on two factors. 1) The size of the planet, 2) Chaotic variables that came into play when the planet obtained it's system of orbit.

The planetary day base starts out at 12 hours.
Small planets roll and additional 2d4 hours
Medium roll an additional 2d4+4 hours
Large roll 1d4x10+20
Giant roll 2d6x10+20

STEP 4: PLANETARY ATMOSPHERE

01-40 NONE! The planet is devoid of any sort of life supporting gases (and most likely any life)>
41-50 C02 (Carbon Dioxide) The planets atmosphere is compose primarily of carbon dioxide, which in the proper placement, can make the planet suitable for photosynthetic organisms, Obligate Anarobes, and facultative anarobes.
51-60 Methane. Plain and simple the atmosphere only supports forms of life that live off the presence of methane.
61-70 02 (Oxygen). The atmosphere is compose primarily of 02. Making it suitable for human and most intelligent life as we know it.
71-80 Oxygen/Methane Combination This planet can sustain human life and methan dependant life. Garudans will find themselves able to breather without the aid of their tanks, thought it will be abit labored (fatigue rate is 50% faster).
81-90 Sulfur Dioxide Like the planet of Venus, this world's atmosphere is perfect for a mega-green house effect. If this roll is made, immediatly make the planet a desert world, because that's about the only thing that could result from this kinda atmosphere. Constant thunderstorms rage across the surface of the planet. Also acid rain falls from the sky every 5d6 minutes lasting for 2d4x10 minutes. Doing 5d6 S.D.C. every minute one doesn't find shelter or protection. Mecha take 1d6 M.D. every 5 minutes in the rain. Temperature on this planet ranges around 900 degrees F (483 C). Even people in full CVR-3 or Cyclones won't last 10 minutes! Even in large destroids or Veritechs they can't withstand prolonged exposure to the massive temperatures, taking 2d6 M.D. for every minute exposed (the damage for the Acid rain and heat is cumulative!). These planets are immensely harsh and only the largest starships are immune to the extreme damage caused by the conditions of these "Death Worlds."
91-00 UNKNOWN!. The gas is some strange new element that is quite unhospitable to most life (including plants & methane breathers). There is a 10% chance this gas will be alike enough to the Garudans atmosphere that they will be able to function fully without tanks or masks.

STEP 4: PLANETARY ECOLOGY

01-15 Desert Planet For what ever reasons, the planet is just a total desert w/ sparse mountainous regions. Very little life is likely to exist, most of it nocturnal or subterranean. Roll another percentile to determine the average daytime temperature. 01-50 Hot (High 110 F, Low 85 F), 51-00 (High 10 C, Low -5C).
16-30 Arctic Planet For what ever reasons, the planet is currently froven over. Like the Desert planet life is sparse, and there are some mountainous regions. High -10 C, Low -50 C.
31-45 Volcanic Planet This planet is a constant hot bed of Tectonic Activity. Across the surface 1 Volcano erupts for 30 minutes every hour. Every 15 minutes there is a quake 4.5d6 on the Richter Scale occurs lasting 2d4 minutes. THe plnaet is covered with mountains but any chance of life existing is nil (.001%). High 200 F, Low 150F.
46-60 Jungle Planet Due to the orbital posistion and atmospheric conditions the planet is a lush tropical one. For travel through the various jungles, use examples from Strike Force & Return of the Masters. Life forms will be many in number. NOTE: Ignore this roll if the planet has no atmosphere. High 90 F, Low 75 F.
61-75 Water World (BACK COPYRIGHT LAWYERS! BACK I SAY!) The plnaet is covered entirely (or almost) by water! There maybe one contienent and sparse island chains (GM's Call). Life underwater will be abundant. Humidity will be very high. High 75 F, Low 60 F. This world can only exist in a Oxygen Atmosphere world (or Oxygen/Methan Hybrid).
76-90 Mountainous Planet The planet at one time or another was plauge by large ammounts of tectonic activity (may have formerly been a Volcano Planet). Caves, large underground caverns, etc. will be abundant. Life will most like be cave dwelling & nocturnal, of course their will be creatures who fill niche's similiar to Mountain Lions & Goats, aswell as birds of prey. Temperature varies with alitudes and area.
91-00 Varied Ecology The planets ecology varies from place to place like Earth. Most likely due to a faulty axis tilt. Life will most likely be abundant. Ignore this roll if no atmosphere is present.

(OPTIONAL)STEP 5: IMPORTANT MINEABLE MATERIALS

The creator can roll on this table as many or as few times as he wants.
01-10 Monople Ore The planet is chockfull of the ore though only to be found on Fantoma. This ore enables unglitched fold travel.
11-25 Titanium-X Deposit. The planet is rich in the needed materials to construct mecha and starships with.
26-35 Helium3 This is an important gas which is required for the operation of any Robotech Fusion engine.
36-50 Crystal Deposit. The Crystals found are needed for laser weapons used by the Robotech Forces.
51-75 Oil & Gasoline Fields As odd as it may sound, gas & oil are extremely important to the maintenance of the fleet. 76-00 Uranium Depleted and active uranium are important parts of different Robotech Weapons. Depleted uranium slugs are used in auto-cannons & gun pods for their high density. Active uranium is obviously required for Nuclear Reflex Weaponry.

(OPTIONAL)STEP 6: UNIQUE ASPECTS OF THE PLANET

The creator can roll on this table as many or as few times as he wants.
01-15 Young The planet is very young in comparison to some planets. 2d4x100 Earth Year.
16-30 Old The planet is quite old, it may only have a few more centuries of life left.
31-50 Faulty Axis The planet is tilted on it's axis, much like Earth. This can cause variances in ecology determined by area and severity of the tilt.
51-65 Eliptical Orbit The planet has an oval shaped orbit around the systems star.
66-80 Magnetic FieldThere is a magnetic field around the planet which disrups all electronic instruments but visuals (that means no radio, radar, & no guided missiles except reflex).
81-90 Mystic Properties Roll on the Mystic Properties table below.
91-99 Last Days The planet is in it's last days of life. The planet is suffering massive Earthquakes range from 8 to 10 on the Richter scale! The planet has approx 4d6+16 Earth days before it explodes (ala Krypton even).
00 PROTOCULTURE The planet is capable of growing pure Flower of Life! This planet has yet to be discovered by the Invid (and may already be occupied by some other form of life), but when they do they will fight with all of their power to claim such a world.

(OPTIONAL)STEP 7: MYSTIC PROPERTIES

I felt this table needed to be added for a sense of completeness with Palladiums strange joy with magic (yuck!). It is suggested you only roll once or twice on this table.
01-30 Moderate Magic Energy The presence of 'magic' energy is the equivalent of Nightbane or BTS Earth.
31-40 High Magic Energy The presence of 'magic' energy is the equivalent of the Palladium World.
41-60 Interdimensional Cross-Roads The planet is in a costant state of space-time inbalance. As such rips in the continium will not be unlikely.
61-80 Crystals of the Four Elements The planet's ecology is balanced by four mystic crystals, one for Fire, one for Water, one for Earth, and one for Wind. Should any of the crystals be shattered, it's specific element will decay (Flames will become weak or die, Water will become stagnant and fish will die, Earth will become infertile, Wind will cease to blow and birds unable to fly). Loss of all the crystals will lead the planet to doom.
81-00 Statues of Balance THe balance of power through the planet is maintained by three statues set in an Equilateral triangle. The statues will we well hidden away. Moving the statues will cause emmense geological chaos throughout the planet.
