Recently I got several of the HARP system books from a friend as a gift (basic rules, folkways, martial law, college of magics), and I like the system overall.
Unfortunately, there are plenty of things that raise small question marks in my mind, and while many have answers on this forum, some don't.
1) Greater Human (or Queequayth) Blood Talent: The fourth option gives 3 points to 2-3 of your stats. This is as compared to the similar options for other races, which improve stat modifiers, and therefore this yields a drastically different feel: choice versus value. On the one hand, it 'only' gives stat points, which immediately and in the long run are less valuable, but you can put them wherever you want. Is this difference intentional, or has it been misprinted?
2) From page 56 of the basic rules: gigantism is a word, and a real-world medical condition, usually caused by a pituitary deformation. 'Giantism' is neither a word, nor a medical condition. Moreover, if you increase the size of a creature by 50% in only one dimension, it will be roughly 50% heavier, not 100%.
3) Some talents are presented as having multiple levels, like regeneration or succor. Others that would seem to follow this same pattern are described separately, such as darkvision (lesser and greater), blazing speed and superior blazing speed, extremely nimble and wildly nimble, etc. By rules as written, it seems a character could double up on certain talents that affect the same combination of skills/effects, but not others. Why the difference? Is this intentional or unintentional?
4) Quiet stride, extremely nimble, and wildly nimble all state that they provide a bonus to stalking maneuvers, not stalking and hiding. Oversight, or intentional?
5) Just out of personal curiosity, can you stack accelerated healing on top of regeneration (minor) to recover 2 Hits/minute (1/minute, doubled by accelerated healing), or is its effect subsumed by the regeneration? If they're separate effects, due to being different talents, do you recover from other effects of damage (skill penalties, broken bones, and the like) at 2, 3, or 4 times the normal rate?
6) Why would anyone EVER take physick?! +10 to healing and all medical skills? Healing is the ONLY medical skill! Physick is a skill specialization masquerading as a separate talent, is what it is!
7) Someone should make isekai reincarnation rules.
