I had to remind Deirdre throughout the game to go to the Gatherer's Garden to buy gene upgrades, because having to buy upgrades was not an intuitive thing to do in the fantasy-world context. It raises an interesting game design question: why would you not just get the upgrades automatically? Why can't the choice be presented to the player in a clear way? In fact, why do games love currency systems so goddamned much?
Deirdre is certainly not suffering from a lack of exploration. Again, exploration is probably her number one interest. But the menus of Gatherer's Gardens &c. aren't interesting explorations: menus are boring, looking through corpses is fun.
