A game of sorts "my rpg"

The baby is asleep and this game is the subject of my idle thoughts. So I thought I'd demonstrate it by making a dungeon crawler game for young children.

I would start by finding inspiration for the game. Say for example one was showing the little ones some miniatures of classic heroes and monsters.

Next would be naming the characteristics.
Muscle = Hitting (or power)
Hands = Shooting (or elegance)
Tongue = Bravery (tongue represents the character's ability not only to talk well but to understand people. In this case we stretch that meaning)
Brain = Thinking or intelligence
(New characteristic) = Defense (optional. This way the players roll to avoid being hit rather than the GM rolling to hit with the monster)

The game mechanics go as follows.

Each characteristic is rated 1, 2 or 3, and that indicates how many dice are thrown. Results of 1 to 3 score 0 points, 4 or 5 score 1 point and 6 scores 2 points. To pass the player must beat the creatures' size value (1 goblin or smaller, 2 roughly human sized, 4 troll, 6 giant) plus 1 point for each advantage you have, minus 1 point for each disadvantage (a mixture of skills, equipment, fictional positioning, injuries and the monster's skills). Depending on how much of a challenge you wish to put on the little players you may give monsters more than one hit point, or not.

Player characters don't have hit points. When they fail a defense roll they get a specific injury or affliction (such as arm wound or afraid of the dark), which the GM uses as a disadvantage to their rolls. The PCs can try to heal themselves or each other if the GM allows it. PCs only die if the little one gets tired of the character or they have too many afflictions and want to start anew.

Then to make a character the players get 10 points to spend on their characteristics, each of which must have a minimum of 1 and a maximum of 3. Also they choose 4 skills, spells, equipment or weapons, which gives them an advantage to their rolls if the choice makes sense (or allows certain actions to be taken, such as casting a spell or climbing with a rope).

If monsters make their own rolls then the GM might want to make most monsters with 7 characteristic points and 2 skills. If not then one should still give them skills. 1 skill for a goblin, such as hiding, and several for a dragon, for example flying, hard skin, fire breath x2 and tail attack.

During the adventure just draw a dungeon as you go and use whatever miniatures you have at hand, throw in an event when you want and have them traverse it using stats when possible. Start with small creatures and train the players to look for advantages by having your goblins (or whatever) look for advantages. Have trolls terrify the PCs with a roar. Stuff like that.

That would probably be all I would need to run a game as and would teach the little ones how to do some basic role play in preparation to starting a D&D group with them as they get older.
