MDA: Human Dynamics Dynamics
Where does the player fit into MDA? • MDA is a cognitive approach. • There are other approaches.
Aesthetics
Mechanics
Dynamics
Game Dynamics • We want to explain and predict the events of the activity. • Science gives us Dynamic Models. “Rules” “Activity” “Fun”
Chance in 36 Die roll Example: Random Variable • This is a model of 2d6:
The “Scourge Factor” How might this fail? SissyFight Is Someone Winning? Team Attack! Let’s gang up!
Example: Greed Catalyst Which game is harder?
Important details • The powerup wears off • Creates an “optimality cliff” • Turns enemies into scoring targets • Encourages riskier play • “Greed Catalyst:” a “gift” that makes the player recklessly greedy.
The powerup changes the dynamics of play by changing the player’s behavior. Could convince players to diverge from a “safer” gang-up strategy.
Perception • I can’t act on what I can’t perceive.
Attribution • How people assign blame or credit.
Fundamental Attribution Error • Our own choices are rational and situational. • Other people’s choices are governed by personality and mood. Players might misdiagnose a “scourge” situation.
Self-Serving Bias • Our successes are deliberate. • Our failures are not our fault.
The Gunslinger’s Alibi • When I win, it’s skill. • When I lose, it’s luck.
Randomness is self-serving. • Player is more tolerant of failure. • Player is more stubborn about his choices. (Confirmation bias) No need to change course in order to bring down the scourge.
Some Aesthetic Implications Aesthetics
Gunslinger’s Alibi • I can feel smart without making you feel dumb. • Only if there’s some randomness. • “Beginner’s Luck” • Wizards’ 70/30 rule
Purloined Letter • Something the player knows about, but still doesn’t see coming.
