This is actually much better...
No time wasted travelling up and down the same pathway to gather materials to build a house for a girl, just to come back and find her peeing on the shore...
On the contrary within the game AI Shoujo with or without game cheats, one never needs to build a house to finish the game task requirements. At the beginning of the game you are forced to fish and cook over an open fire, beyond that you are awarded a place to stay by the merchant. Free home beginning of the game after leaving the beach landing point where you will later build a bridge to connect the game map. Crafting materials required for task completion are in the general vicinity of the required task. It is a survival game, not an adult vacation until MC finishes all tasks. BTW if you never build a house any AI girl in game will end up living at the ruins as there is plenty of everything there.
It all depends on the primary focus of one who plays the game. I personally hate collecting anything so I turn on the cheat that gives me 1000 of everything. I give the AI girl(s) the very best tools and very high intuition. I stock the food pantry with hundreds of cooked meals and ingredients, and fresh water at merchant house (consequently filling all game pantry) girls can cook and eat at merchants or ruins, bathe anywhere.
I have played the game many times with different scenario and prefer to have only one girl until all MC tasks are complete. Once all tasks are complete you can train a harem to your wildest desire to roam your mansion on Housing Island.
Only have one AI girl in game and she never wants to H? That is fine too. Give the merchant 600 point value more for the least expensive item she offers for sale. She will love you long time any time you ask.
