Mutants & Masterminds Second Edition
Action / Adventure (Superheroes)
Attribute/Stat Based (STR, CON, PER, etc) Dice (Primarily d20) Point Based (allocate points to get skills, powers, etc) Progression Tree (Skills, professions, magic abilities, etc.) Skill Based (buy or gain skills)
The second edition rules of Green Ronin's superhero game. The True20 system has its origins in Mutants and Masterminds (2nd edition.) Visible similarities include the use of a single d20 and the save system for damage. However, True20 is not a point based system so dramatic differences exist in the character creation and the characters that result.
