you will need to start with the base mod. You need that one no matter whether or not you decide to use any of the others or not.
Then when you have time, have a look at the different aspects the other ones deal with. If you click on the link called 'intereactions' under the heading 'documentation', you will get a list of all the interactions available on the master controller. for example:
- Lists information on the lots in town
- Personalities NEW
- Lists a summary of the personalities operating in town.
- Module: MasterController Progression
so, for example, the interaction 'lots' which lists information on the lots in town, is in the base mod, but the part that lists a summary of the personalities operating in town, comes with the Progression module.
If you have a look at the whole list, you will be able to see whether or not you want any of the other modules.
