One more Unova thing that could be interesting as a side scene. There is a mall that the MC could take some of the girls to explore, to see if there anything that catches their interest. Like the walk garden back in Sinnoh.

True, not a lot of legendaries to compete in it at this stage in the journey. Not to mention that it'll be hard to turn it into a series of mini-games. But if there must be pokemon to fuck there, you could always have some fighting type pokemon competing there. Just need to complete their challenge, before you could fuck them.
