SIZE MATTERS

In the Gravity Age setting size matters or at least it does for player characters.  The Starfinder Role Playing Game most playable races are small or medium-sized creatures and the effects of their size have already been baked into the stats blocks for each race.  However, if you are creating a mutant character or NPC that is of abnormal size for their race or capable of changing their size it is necessary to embrace the concept that size matters.

New rules have been introduced (old rules have been carried forward) to compensate for size differences between mutants and common members of their own species.  Density Alteration, Dwarfism, and Gigantism all use a mechanic similar to the enlarge and reduce mechanics introduced in the original SRD.  These modifiers were updated for compatibility with the Starfinder Roleplaying Game.

The new “Creating Monsters and other NPCS” mechanic assumes the creatures size is already built into the creatures base array and CR so it is not necessary to add a “Size Graft”.  However, if a creature has the Density Alteration, Dwarfism, or Gigantism mutations the bonuses and penalties should be applied to distinguish it from regular members of their race.
