-Functional Brothel - A lot of people have made requests to extend the brothel whether it is to pay for sex there, add extra quests, make the mistress a chastity keyholder, and so on. To play devil's advocate, Strive is about making your own harem than paying for sex. I've added some quests to the brothel in my mod and I expect to add more.
-Alchemy Assistant - I've got code for a basic alchemy assistant in my mod already and that's free for people to copy.
-Gardens - Yes I've also had some ideas about buying a garden, appointing a gardener, growing alchemy stuff. Not a priority for me.
-Mansion attacks and Mansion defences - Mansion attacks have been requested before and you've made it look a lot better by suggesting defences as well.
-Wimborn doesn't need a new lowbie area as Wimborn Outskirts is really generous already, in the big scheme of things.
-Arena and Adventurer's Guild - Both fair ideas if someone is willing to code them.
-Enchanter - Something else that has been requested before. An artifact refiner that changes a bonus to its maximum might be more promising as it doesn't break game balance.
