In the 1980s there was a french TV series called "Once upon a time... life". In this series the main characters were blood cells and vitamins and what not. And the baddies were Bacteria, Viruses, poison etc. So with this as an inspiration I've created a role-playing game (based on d6 for simplicity) set in this cartoon world.
If you don't know what I'm talking about have a look here, and here is the homepage of the producer of the series.
This system is based on the D6 system by WEG (now OpenD6)
These Bactera are pretty strong (Photo (C) Procidis)
Skills have a base score equal to the attribute that they are listed under. They can be increased by experience.
Close combat
This skill is used when you are attacked by bacteria or viruses.
Climb/Jump
This is used to get across hindrances like a blood clot or a ruptured vein etc.
Lift

Endurance
Used to perform heavy work over long time periods.
Dodge

Sneak
Used to sneak past bacteria or police (white bloodcells). This skill can also be used to hide and to camouflage yourself to something else.
Survival
This skill is used to find nutrients outside of the bloodstream (where there is a rich variety of nutrients).
This skill can also be used to gain knowledge of the tissue you are in. /"Oh so this is the liver. Riight"/
A third use of this skill is used to survive in totally hostile environments, like on the skin, etc.

These guys are generally strong and dumb. They spend their days hauling O2 from the lungs and CO2 to the lungs. CO2 is quite heavy, while O2 is quite light.
Players who choose this character type get to assign 2D in any of the attributes. This can be split however the player wishes.

The policeforce of the body. They Are very physical and love to kick bacterial but! They have a special talent. They can do mitosis, that is split and double them selves. It takes 4 turns to perform a mitosis. When this is complete the character is essentially duplicated and the player gets to control both clones. They can also attack at very long ranges

These are also part of the body's defense force. T-cells co-ordinate the defense forces and have the knowledge to kill the body's own infected cells. These are the only ones that can attack a virus infected cell. The virus infected cells usually become factories that create more viruses. To kill an infected cell they need to detect it and the use a targetted attack on it. T-lymphocytes can also do a mitosis.
