What're your ideas for the alternative classes? It shouldn't be hard to put a check in their for specific costs for different player specialties.
Viewing post in Aric's Expansion Rebred
Breeder - of course, plays as normal
Commander - extra xp and learning points for slaves; however slaves cost more
Lab Master - Free Lab; more modification = higher selling price; slaves faster disobedience
Cultist - can create slaves (cost a lot of mana)
As well as modifications to existing classes
It just seems the vanilla Mansion.gd is a house of glass.
