I’m not even going to try to follow the implications of that statement, because I disagree with your premise. Games are interactive, sure. But the creation of a game is NOT participatory.
Oh dear, a food analogy. I mean, the taste of food and the challenge level of a game are both subjective? That’s about all they have in common.
Look, a game designer engineers an experience based on the concept of enjoyable frustration. Right? As a player/customer/consumer, it’s not my job to engineer either element of that experience. The more accurate analogy would be me going into the Thai restaurant, ordering the pad kee mao, and the chef replying, “Coming right up! But first, I need you to tell me how to make it?”
Here’s a better analogy if you want to get reductionist. When I play an RPG, I know a kobold has a certain number of hit points. I know a sword does a certain amount of damage. The game designer combines these elements into an experience. Maybe he throws a goblin me, which has more hit points. Scary! Maybe I get a +1 sword to make it easier to kill monsters. Cool! Game design 101.
Now imagine that the game designer instead asked me how many hit points the kobold should have. Imagine that he leaves that up to me. Do I want them to have 2, 3, or 4 hit points? The experience of getting the +1 sword is completely subverted when I can just decree that all kobolds have fewer hit points. The experience of fighting the tougher goblin is subverted if I decreed that the kobolds have more hit points.
That’s simplified, of course, and plenty of games have smart and carefully built ways to adjust the challenge level so a wide range of people can play. But plenty of games also ignore the issue entirely because they can’t be bothered to work out how to tune enjoyable frustration, so they just shrug and dump it in the player’s lap. Which plenty of players don’t mind, by the way. I think a lot of players are happy to just do the developer’s job for them, because they’re not interested in how a good chef might make pad kee mao. They just want to taste the same thing they had at their favorite restaurant, so they gladly tell the chef how to make it when he asks.
Boom! Food analogy brought full circle!
