'''Rolemaster''' is a fantasy RolePlayingGame created in 1980 by Iron Crown Enterprises. As ''TabletopGame/DungeonsAndDragons'', it is a game system with classes, races, levels and experience points (no {{Character Alignment}}s, however). Unlike D&D, it provided lots of optional rules with many detailed tables (one for each of the several dozen weapons) from the beginning. There are dozens of magic-using classes who have hundreds of spell lists available with more than 2,000 spells altogether. Some fans and non-fans call RM "Rulemaster" or even "Roll-Master" for this reason; another popular nickname is "Chartmaster". The game has been through several editions, the most recent being ''Rolemaster United'' in 2012.

The game ''TabletopGame/MiddleEarthRolePlaying'' by the same publisher is a streamlined version of Rolemaster.

!!This game provides examples of:

* ArmorIsUseless: Due to open-ended rolls and the critical hit system.
* AttackPatternAlpha: Combat Languages Type 1 in the Arms Companion supplement.
* CharacterLevel: Standard for games of its time period.
* ClassAndLevelSystem: Ditto.
* CriticalFailure: You are capable of failing in many specific ways. The fumble chart is as large as any of the CriticalHit charts.
** Nearly anything you can do can kill you if you roll bad enough. A KillerGM will make players roll to tie their shoes.
-->''"Your fall turns into a dive. You crush your skull and die."''
* CriticalHit: Combats are often ended by critical hits rather than mere hit point loss.
** Critical hits, in fact, are the rule rather than the exception. Whereas in most games a critical hit happens once every 10-20 attacks or so, and results in a simple increase in inflicted damage, each attack type in Rolemaster has an entire ''table'' for determining the effect of a critical hit, at 5 or more different levels of ''crit severity''. A hit that doesn't result in a crit is little more effective than a miss.
-->''"Strike through ear destroys brain. The unfortunate lummox dies instantly, and any ear wax is removed."''
* DiminishingReturnsForBalance: The skill system
* EverythingTryingToKillYou: More a case of Almost Anything CAN Kill You - with open ended attack rolls and instant death criticals, it was entirely possible for your level twenty hero in magical full plate armour to get his head torn off by a kitten.
* GoldSilverCopperStandard: Or in this case, mithril-gold-silver-bronze-copper-tin-iron standard.
* HitPoints: Called "concussion hits". When your hit points reach 0, you're unconscious -- it takes a lot more damage to die. The main form of character injury comes in the effects of various {{critical hit}}s, such as loss of limbs, stunning, instant killing, a whole variety of bleed effects, and other "crunchy bits".
* KryptoniteFactor: Some editions have included detailed elemental rules. One section is metals that have elemental properties. Striking an elemental creature (which can include dragons) with a weapon of opposite elemental properties automatically converts all critical hits to ''slaying'' criticals, which, on the normal critical scale of 1 to 5, are about a 9.
* LinearWarriorsQuadraticWizards
* LoadsAndLoadsOfRules: A great deal of these are optional, though also add to realism.
* NonCombatEXP: Iron Crown Enterprises' games (''Rolemaster'', ''Space Master'', ''Cyberspace'', etc.) often gave experience points for non-combat actions, such as coming up with useful ideas, performing movement maneuvers (e.g. running), traveling (5 XP per kilometer), using spells or psionic powers, performing research and building or repairing items.
* PerpetualMotionMonster: The Black Reaper, an extremely powerful demon that is commonly used to guard items or places. Once disturbed, it will never stop pursuing the offender until he or she is dead. It is immortal and doesn't need food or air, and is never bored. When it follows its soon-to-be victim, it will just walk underwater through oceans or use its magic axe to tunnel through all but the hardest material.
* PitTrap (with SpikesOfDoom at the bottom): In the ''Arms Companion''.
* SpellLevels: Spells were arranged by level within spell lists. In order to cast a spell, a character's skill rank for that spell's spell list had to be greater than or equal to the spell's level.
* SurpriseSlideStaircase. In the ''Arms Companion''.

* HideousHangoverCure: ''Jaiman: Land of Twilight''. Eating the fruit of the Siene bush cleanses the body of any intoxicant (such as alcohol) in seconds ''and'' can cure hangovers, thus making it a rare example of both types of this trope.

!!The ''Spacemaster'' system and its ''Privateers'' campaign setting have the following tropes:

* AlcubierreDrive: ''Privateers'' campaign setting. The Quantum Drive uses quantum fields to contract space in front of the ship and dilate space behind it, allowing the ship to effectively exceed the speed of light.
* AmmunitionBackpack: ''Privateer'' campaign setting. Backpack energy cells can hold 35,000 energy units and are often used to power large weapons.
* EscapePod: ''Privateers'' campaign setting. Life pods are small, five person ships that only have maneuvering thrusters and are usable only if in orbit. They have heat shields and parachutes for atmospheric re-entry.
* {{Flynning}}: ''Privateers'' campaign setting. The Swashbuckling skill allows the user to perform elaborate maneuvers with his melee weapon, including flourishes and feats of weapon control (such as recovering a dropped weapon).
* IntrinsicVow: ''Privateers'' campaign setting. The Telepathy Psychic skill had several powers with this restriction.
** Behavioral Trigger: If the psychic tries to get the victim to do something that is totally out of character (such as betraying everything they care about) the Task Difficulty is Sheer Folly (-50% to chance of success).
