Converting Marvel Super Heroes (MSH) to The Basic System (TBS) or Visa Versa

 

Conversion between MSH and TBS is actually quite easy with the addition of benchmarks to the TBS free download. The table below shows MHS Abilities and their TBS Main Stat equivalents:

 

MHS Ability

Fighting

Agility

Strength

Endurance

Reason

 Intelligence

Charisma

Speed

 

Unless otherwise noted, to convert an MSH Ability Rank to a TBS Main Stat Score, simply add four (+ 4) to the given MSH Ability Rank, and then adjust the result up or down to the nearest TBS Benchmark. This formula breaks down with stats above 90; in those cases, use TBS benchmarks as guides. Translations of MSH Ability Ranks to TBS benchmarks are given below:

 

MSH Ability Rank

Feeble (2)

Poor (4)

Typical (6)

Determining Charisma

 

MSH doesn’t have an exact equivalent to the TBS Charisma stat, but by averaging Intuition and Reason, one might arrive at a pretty fair approximation:

 

(MSH Reason + MSH Intuition) / 2 = TBS Charisma 

TBS Charisma and MSH Popularity

 

For every ten (10) points of MSH Popularity (rounding up), add one (+1) point of TBS Charisma to the above result.

 

Determining MSH Intuition using TBS Charisma and TBS Intelligence

 

Use the formula below to approximate an MSH Intuition Rank:

 

(TBS Intelligence x 2) / TBS Charisma = MSH Intuition

 

Determining TBS Speed

 

MSH does not use a Speed attribute. The MSH rules set assumes that most characters can move up to two areas per six-second turn. Characters may suffer temporary Endurance losses to move farther or faster. For the sake of argument, assign the character being converted a base Speed of ten (10), adding an additional three points (+3) for every MSH Endurance Rank the character has above Good.

 

Determining MSH Fighting using the TBS physical Main Stats

 

Fighting in MSH is a measure of a character’s raw fighting ability. If converting a Martial Artist character from the GU: Kamikaze Edition game, MSH Fighting equals one half of (1/2) the character’s Chi. If using the TBS free download, use the average of TBS Strength, Agility, Endurance and Speed:

 

(TBS Strength + TBS Endurance + TBS Agility + TBS Speed) / 4 = MSH Fighting

 

Converting MSH Karma to TBS Experience Points

 

 If using the TBS point based game option, divide MSH Karma by fifteen (15) to determine how many TBS Experience Points; otherwise multiply MSH Karma by two (2) to determine TBS Experience Points and TBS Level. 

 

Interpreting MSH Resources

 

A character’s disposable income in U.S. dollars is approximately represented as the MSH Resources rank multiplied by one hundred (100). 

 

Converting Talents and Skills

 

These elements are perhaps some of the easiest to port between systems because MSH Talents are categorical and broad-based like TBS Skills. Although MSH Talents do not typically have ranks, corresponding TBS Skill levels can be determined based on what is known of the character.  

 

Converting Powers

 

There is no hard and fast way to convert powers. Just approximate the effects between both systems. Some helpful hints:
