As I side project, I've been developing guidelines to relatively easily convert V&V characters into the Marvel Super Heroes RPG that was also popular during the 1980s. Those were the only two game systems that I've ever played regularly. If there is interest, here, I could post those guidelines on this forum as a series of posts within a thread in the days ahead.

Since the revised edition of Villains & Vigilantes and the original Marvel Super Heroes RPG were popular around the same time, let's begin by determining a character's Popularity score before moving to the FASERIP abilities and super powers.

POPULARITY
For V&V heroes, start with the character's Reaction from Good modifier (which is usually a positive number) and add the character's Level. Multiply that total by 2.

For villains, start with the character's Reaction from Good modifier (which will usually be a negative number) and then subtract the character's Level. Multiply that total by 2.

EXAMPLES
Manta-Man, the heroic leader of the Crusaders, has Reactions from Good: +3. He is 6th Level. In MSH, Manta-Man has Popularity 18

Temper, a member of the evil Crusaders, has Reactions from Good: - . He is 1st Level. In MSH, Temper has Popularity -1.

AGILITY
Villains & Vigilantes and the Marvel Super Heroes RPG both use an ability score called Agility. I suggest these guidelines when converting an Agility score from V&V into an Agility rank in MSH.

0-5 = FEEBLE
6 -8 = POOR
9-11 = TYPICAL
12-14 = GOOD
15-20 = EXCELLENT
21-32 = REMARKABLE
33-47 = INCREDIBLE
48-65 = AMAZING
66-86 = MONSTROUS
87+ = UNEARTHLY

EXAMPLE
The V&V character Skyhawk has Agility: 18. Converted into Marvel Super Heroes, Skyhawk has an EXCELLENT rank in Agility.

ENDURANCE
Villains & Vigilantes and Marvel Super Heroes both use an ability called Endurance. After a close review of each game system, however, I recommend using the Healing Rate from a V&V character sheet to determine that character's Endurance rank in MSH.

0.1-0.3 = FEEBLE
0.4-0.6 = POOR
0.7-1.1 = TYPICAL
1.2-1.5 = GOOD
1.6-2.3 = EXCELLENT
2.4-5.9 = REMARKABLE
6.0-11.9 = INCREDIBLE
12.0-23.9 = AMAZING
24.0-47.9 = MONSTROUS
48.0+ = UNEARTHLY

EXAMPLES
The V&V outlaw Mammoth has a Healing Rate of 4.8, while his hired stooge 'Heater' Jenkins has a Healing Rate of 1. Converted into Marvel Super Heroes, Mammoth has an Endurance rank of REMARKABLE and Jenkins has an Endurance rank of TYPICAL.

INTUITION
When converting a character across game systems, determine the Intuition rank in Marvel Super Heroes by looking at the V&V character's Detect Danger % (including modifications from powers and weaknesses). If a V&V character's Detect Hidden % is higher, use that number instead.

0-5% = FEEBLE
6-11% = POOR
12-15% =  TYPICAL
16-19% =  GOOD
20-32% =  EXCELLENT
33-48% =  REMARKABLE
49-64% =  INCREDIBLE
65-80% =  AMAZING
81-96% =  MONSTROUS
97% +  = UNEARTHLY


EXAMPLE
Prince Kalm of the Aquin underwater kingdom has a 16% to Detect Danger in V&V. When converted to MSH, Prince Kalm has an Intuition rank of GOOD.

ANIMAL STATS
Prince Kalm also has the mutant power to communicate with oceanic animals, which brings me to an important note about the different approaches to animal stats across systems.  In V&V, animals and other creatures with the an Intelligence score of zero have a 0% to Detect Hidden and 30% chance to Detect Danger. When converted to the MSH system, wild animals default to a FEEBLE rank in Reason, Intuition and Psyche. Super-pets trained in scouting, on the other hand, sometimes have an Intuition rank as high as REMARKABLE.

RESOURCES
The Villains & Vigilantes revised rulebook has a formula to calculate a character's annual income and available cash, including the possibility of an inheritance. Instead of using that precise system to determine what a V&V character's Resources rank would be in Marvel Super Heroes, I think it works best to make a judgment call based on the character's background information. When in doubt, assign the rank TYPICAL.

Example
Sandra Montuori , a.k.a. Shapeshifter of the Destroyers, owns one of the world's largest trade and industrial corporations. The Destroyers' headquarters is located in the top three floors of the Montuori Traade and Industries Building, a 40 story skyscraper.

Shapeshifter's wealth seems to match the MSH description of the Resources rank INCREDIBLE (large corporation).

TELEPORTATION

Villains & Vigilantes has a complex system for determining the distance a character can teleport, based on the character's current Power score and the set PR cost for that power. When converting a V&V character into Marvel Super Heroes, my recommendation is to assign the character a consistent Teleportation rank in MSH based on the character's PR cost for teleportation in V&V.

PR 1 = FEEBLE (2 areas)
PR 2 = GOOD (10 areas)
PR 3 = UNEARTHLY (100 areas)
PR 4 = CLASS 1000 (1000 areas)
PR 5 = CLASS 5000 (5000 areas)

Although the exact distance of an "area" in the Marvel Super Heroes RPG is relative, with areas of terrain on game maps taking up less space indoors or in cluttered environments than outdoors, most of the MSH city maps show a typical city block at 2 areas long, with 1 area for the large intersection between blocks. If we average 12 blocks per mile, that gives us an average mile has 36 inches. With 5280 feet in one mile, one MSH area measures a length of 146.67 feet.

V&V, on the other hand, uses the term inch (often abbreviated ") to represent 5 feet. That means that  29" in V&V maps to approximately 1 area in MHS.
