update will upgrade your Creatures 2 Digital DNA to Genome 54 (please note
that if you have Creatures 2 version 1.038 or above, you do not need this
update). The Norns supplied in this pack are designed to be more robust
in general as well as have improved behavior. Many minor tweaks have been
made, and for the technically minded and those interested in the details
of what we've updated, the major changes are detailed below:
The structure of your
Norns, Grendels and Ettins is based on Digital DNA -- a genetic
structure that describes the building blocks of the creatures themselves,
including their biochemistries, brain lobes, instincts and the poses they
can get their bodies into. The below list describes the changes we've
made since the original release of Creatures 2. If you'd like to learn
more about why these changes were made, click here to read the Genetics
Update FAQ (Frequently Asked Questions).
- Some drives have
been given priority over others, so that the primary drives (eating
and reproducing) which keep the species alive, are given priority over
secondary drives (eg NFP, boredom) in dictating the activity of a Norn.
- Norns now require
a larger amount of food in their stomachs to feel full.
- The problem with
causing damage to the uterus instead of to the heart when Norns become
obese has been fixed. They also need to be a lot more obese now before
any damage will be caused.
- The feeling of
fullness depletes hunger. Fullness now depletes less hunger than before,
so if the Norn snacks it will not necessarily totally deplete its hungry
feeling, just slightly reduce it.
- Norns get more
nutrition from eating now. This means that the rate at which they eat
should better satisfy their energy requirements.
- A new regulation
mechanism ensures that glycolysis only burns glucose when the Norn is
low on ATP.
- Anaerobic respiration
has been made more biologically realistic (many thanks are extended
to Lis Morris for her contributions to this).
- The feelings of
crowdedness and loneliness wear off faster than before.
- Various stimuli
have been changed to bring the amounts of punishment and reward more
in line with the rest of the stimuli. This means that the stimuli should
now contribute about equally to the learning process.
- Norns have a couple
of new instincts to encourage them to do be more active when they're
- Muscle tissue/protein
use balance has been adjusted. This should increase a creature's life
In addition to the
above changes, the bloodstream now has an oxygen-carrying capability,
to allow the Norn a few more seconds of life underwater. Many thanks are
extended to Lis Morris for providing us with the genes for this.
