Because it will feel weird if the gardener askes noobish questions. I was thinking of making Konohamaru as the NPC who askes the questions.
"Since the gardens are for adults only, you can talk about anything here."
"You can get undressed in the Gardens"
"You have have a romantic love scene in the gardens"
Those aren't noobish questions? ^.^ The gardner does ask quesitons that new players wouldn't know and veterans would know ^.^
Because it's going to be a question with multiple answers to choose from & each of them sounds like the right answer. It will be hard to get it right just by guessing. They might even learn by remembering the right answers.
Just like players can learn by answering quesitons from the gazebo =) I'm not saying it's a bad idea, I'm just saying a new module isn't needed when you can just add them to the question arsenal of the gardner.
