New World Monkeys in GURPS

New world monkeys are animals of the jungles of South America and Central America. The larger species get about by carefully moving from branch to branch, using their feet and prehensile tails to maintain a grip. Smaller species usually lack prehensile tails and grasping hands, and leap and scramble from tree to tree, running along, over, and between branches with agility. To represent these locomotor abilities in game terms, they have the advantage "Brachiator" (a misnomer because they do not actually brachiate) so that they need not make rolls for jumping between branches and vines and do so with speed and agility, Clinging(requires hand-holds) so that they need not make climbing rolls for moving along rough, grippable surfaces and can so so with speed and agility, Terrain Adaptation (uneven) for jumping and clambering over jumbled surfaces without penalty, and Perfect Balance for running along branches without making rolls to see if they fall off.

New world monkeys have good vision, although most species are red-green colorblind. They seem to capture an intermediate position in the evolution of full color vision, for some species many females may have trichromatic vision while other females and all males have bichromatic vision. These monkeys have good hearing, but like most primates their sense of smell is rudimentary compared to other mammals. Their sense of touch is concentrated in their hands, which are used to probe and explore their world.

Monkeys always live in groups. They get depressed and lonely when alone. However, the nature of the group dynamics varies considerably from species to species. The details are given in the species descriptions. For convenience, some shorthand terms are used to define social systems common among monkeys - see the description of social systems given in the old world monkey section. They also have many of the same personality traits, which can make interacting with monkeys quite a chore.

The radio button entries in the table above give typical sizes of the monkey species of the selected sex. If you want a larger or smaller specimen, enter the weight in kg manually.

The Captive checkbox is for animals that have been kept in captivity all their lives, without the ability to hone their reflexes, muscles, and skills like thier wild relatives. It would be appropriate for pets and zoo animals.

Marking the T? checkbox will give you the stats in template form with all costs listed, otherwise you get a stat sheet as for a character.

Marking the HR? checkbox will print the information using all my house rules. Otherwise, the stats will be as compatable with plain vanilla GURPS as possible (although several custom advantages and disadvantages will be present, see my Traits page).
